Item The influence of the environmental factors on the accumulation patterns of toxic elements in Plantago lanceolata sampled in the area under strong anthropopressure(Elsevier Ltd., 2024) Jordanovic, Jelena S.; Serbula, Snezana M.; Markovic, Mirjana M.; Radojevic, Ana A.; Kalinovic, Jelena V.; Kalinovic, Tanja S.The study aims to explore the environmental factors which activate accumulation abilities of Plantago lanceolata in the research area under strong anthropopressure resulting from the long-term pollution originating from copper mining-metallurgical activities in Southeastern Europe. Sampling was performed at the most endangered sites regarding its proximity to the major and/or secondary pollution sources, as well at the control site. The content of toxic elements (Al, Cu, Fe, Mn, Ni, Pb and Zn) was determined in the roots, leaves, stalks and flowers of P. lanceolata. The anthropogenic origin of environmental contamination was denoted through the high concentrations of Cu, Pb and Zn in the leaves of P. lanceolata, reaching toxic levels, combined with the enrichment of plant parts (Enrichment factor >2), especially with Cu (as well as with Al, Fe, Ni and Zn) in samples from the immediate proximity to the copper smelter or at the prevailing wind directions. Biomonitoring potential, assessed through the correlations between toxic element content, as well as the values of Enrichment factor, was indicated for roots (in the case of Cu), all the aboveground plant parts (Fe) and stalks (Zn). The results have shown that the contents of toxic elements in plant parts as well as phytoremediation of P. lanceolata were dependent on soil element content, soil physico-chemical properties and soil enzyme activities, which were regarded as the main environmental drivers affecting phytoremediation ability. The analysis of biological factors (bioconcentration, translocation and bioaccumulation factor) indicated exclusion strategy and possible usage of P. lanceolata in phytostabilization of Zn. The results indicated that the study area is 'environmental hotspot' with potential threat to human health due to the high levels of bioaccumulation of the investigated toxic elements in P. lanceolata parts.Item Case study on metal(loid)s distribution in linden tree parts, in areas with hight environmental pollution(University of Belgrade, Technical Faculty in Bor, 2025) Kalinović, Tanja; Radojević, Ana; Kalinović, Jelena; Jordanović, Jelena; Šerbula, SnežanaThe investigation focuses on the distribution of Al, Fe, Cu, Zn, Pb, As, and Cd, in the roots, branches and leaves of linden tree, a very common plant species used in traditional medicine, sampled in the area affected by pollution from the mining-metallurgical facilities for copper production, and one unpolluted zone. Plant samples were collected and processed following the established scientific methods, while concentrations of metal(loid)s were determined using the ICP-AES. Distinct patterns in the metal(loid)s distribution in the linden parts were revealed, which varied depending on the environmental pollution levels, highlighting obvious differences between the polluted and unpolluted zones.Item Comparative assessment of potentially toxic elements bioaccumulation and biomonitoring ability using rosehip, hazelnut, and black elder leaves(Crnogorsko društvo za koroziju, zaštitu materijala i zaštitu životne sredine, 2025) Šerbula, Snežana; Kalinović, Tanja; Radojević, Ana; Kalinović, Jelena; Jordanovic, JelenaThis paper aims to evaluate and compare the environmental role of the rosehip, hazelnut and black elder, in areas with various anthropogenic sources of pollution. In addition to the essential elements for plants such as Ni, Zn, Cu and Fe, the leaves of the studied plant species contained certain amounts of toxic or non-essential elements such as Cd, As, Pb and Al. The concentrations of the analysed elements in the hazelnut and elder leaves from the urban-industrial (UI) and rural (R2) sampling sites stood out in the box plot analyses by the highest number of outlying (mild and extreme) data points. Cu and Pb were the elements with the highest values of the Enrichment factor (EF), in the leaves of the studied plant species, while enrichment was also noted for Zn, Fe, Al, As and Cd, depending on the sampling site and plant species. The highest EF values were calculated for the samples from the UI and R2 sampling sites. The rosehip, hazelnut and elder leaves have a good retention capacity for particulate matter originating from the air containing potentially toxic elements (PTEs), and thus represent green resources for monitoring and mitigation of environmental pollution.Item Potential of using zinc processing tailings (ZPT’s) in the production of burnt clay bricks(University of Belgrade, Technical faculty in Bor, 2025) Messai, Ali; Berrekbia Linda; Meramria, Ikram; Menendez-Aguado, Juan Maria; Fernandez-Perez, Begona; Nikolić, Vladimir; Trumić, Milan; Boustila, AmirZinc processing tailings (ZPTs) from the Kharzet Youcef processing complex (Setif- Algeria) are mainly stockpiled in tailings dumps without use, occupying a significant area with potentially influencing the environment and human health. Incorporating ZPTs in building materials manufacturing is an effective solution to meet the dual objectives of environmental protection and economic development. The study investigates the influence of integrating ZPTs to partially replace clays and firing temperature on the physic-mechanical properties of fired clay bricks (FCB). Microstructural, chemical, and mineralogical analyses of ZPT and clays were carried out by SEM-EDS, XRF and XRD, respectively. Seven mixtures were produced with various percentages of ZPTs added to clays (0%, 5%, 10%, 15%, 20%, 25% and 30%) and were fired to three different temperatures (950, 1000 and 1050 °C) at a ramp rate of 5 °C. Physic-mechanical tests were carried out on different brick specimens, and the results obtained showed the FCB incorporated with 30% of ZPTs produced the highest flexural strength of 6.24 MPa, compressive resistance of 29.78 MPa, bulk density of 1.37 g/cm3 and water absorption of 15.1% at 900 °C. Therefore, recycling ZPTs for FCB manufacturing is a feasible alternative waste disposal solution for sustainable development while reducing negative environmental impacts.Item Proposal of a Method for Calculating the Bond Work Index for Samples with Non-Standard Feed Particle Size Distribution(MDPI, Switzerland, 2025) Nikolić, Vladimir; Medina Pierres, Jesús; Sanchez Calvo, Maria; Menendez-Aguado, Juan Maria; Trumić, Milan; Trumić, Maja; Milošević, VladanDetermining the Bond grindability test in a ball mill is one of the most commonly used methods in the mining industry for measuring the hardness of ores. The test is an essential part of the Bond work index methodology for designing and calculating the efficiency of mineral grinding circuits. The Bond ball mill grindability test has several restrictions, including the sample’s initial particle size distribution (PSD). This paper presents a method for calculating the Bond work index when the Bond ball mill grindability test is performed on samples with non-standard PSD. The presented equation includes a correction factor (k) and is applicable only for P100 = 75 μm. The defined method is then compared with methods proposed by other researchers, and conclusions are drawn as to which method results in less deviation. The presented model resulted in a mean square error of 0.66%.Item Utilisation of Zinc Processing Tailings (ZPTs) in Fired Clay Bricks Manufacturing: Case Study(MDPI, Switzerland, 2025) Messai, Ali; Menendez-Aguado, Juan Maria; Berrekbia, Linda; Meramria, Ikram; Fernandez-Perez, Begona; Nikolić, Vladimir; Trumić, Milan; Boustila, AmirZinc processing tailings (ZPTs) of the Kharzet Youcef processing complex, Setif, Algeria, are mainly stockpiled in tailing dumps without use, occupying significant surfaces and negatively influencing the human environment and health. Incorporating ZPTs into building materials manufacturing is an effective solution to meet the dual objectives of environmental protection and economic development. This study investigates the influence of firing temperature and integrating ZPTs as a partial replacement for clay on the physic-mechanical properties of fired clay bricks (FCBs). Microstructural, chemical, and mineralogical analyses of ZPTs and clay were carried out by SEM-EDS, XRF, and XRD, respectively. Seven mixtures were produced with various percentages of ZPTs added to clay (0%, 5%, 10%, 15%, 20%, 25%, and 30%) and were fired at two different temperatures (900 and 1000 °C) at a ramp rate of 5 °C. Physic-mechanical tests were carried out on different brick specimens, and the results obtained showed that the FCBs incorporated with 10% of ZPTs produced the highest flexural strength of 6.24 MPa, compressive resistance of 29.78 MPa, bulk density of 1.37 g/cm3, and water absorption of 15.1% at 900 °C. Therefore, the recycling of ZPTs for FCBs manufacturing is feasible and an effective alternative waste disposal solution for sustainable development while reducing negative environmental impacts.Item Influence of pre-deformation on mechanical properties and microstructure of EN-AW 7075 aluminium alloy(Materials Research Society of Serbia, 2025) Kovačević, Avram; Stamenković, Uroš; Nedeljković, MilanThis study investigates the changes in mechanical properties and microstructure of the EN-AW 7075 aluminum alloy after thermomechanical treatment. The treatment included cold plastic deformation, induced by rolling prior to artificial aging at a temperature of 150 °C for 30 minutes. The variations in hardness and impact toughness were monitored depending on the applied thermomechanical treatment conditions. Hardness was determined using the Leeb method, while impact toughness was measured using the Charpy method. The lowest hardness values were recorded in the annealed condition (Temper O state), while the highest impact toughness was observed in the quenched condition (Temper W state). The applied cold plastic deformation induced before artificial aging significantly increased the hardness of the investigated alloy, accompanied by a progressive decrease in impact toughness. Optical microscopy was used to analyze the microstructural changes during the thermomechanical treatment. Precipitates of various sizes and morphologies were observed in the alloy structure. The annealed condition was characterized by poorly defined grain boundaries and coarse secondary phase particles uniformly distributed within the matrix. Cold plastic deformation before aging resulted in a structure oriented in the rolling direction and refined secondary phase particles.Item Thermal Properties and Microstructure Evolution of the as‑cast and Annealed Al–Cu–Si Eutectic Alloy(Springer Nature, 2025) Manasijević, Dragan; Marković, Ivana; Cimpoesu, Nicanor; Chelariu, Romeu; Stamenković, Uroš; Balanović, Ljubiša; Gorgievski, MilanThe Al–28%Cu–6%Si (mass%) eutectic alloy represents a possible high-temperature phase change material (PCM) for latent heat thermal energy storage (LHTES). In this paper, its microstructural characteristics and thermal properties were examined in the as-cast and annealed conditions using scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDS), differential scanning calorimetry (DSC), and light flash method. The microstructure of the studied alloy consists of (Al) solid solution phase, θ-Al2Cu intermetallic phase, and (Si) phase. The annealing at 450°C for 50 h led to significant changes in the morphology of the θ-Al2Cu and (Si) eutectic phases. The temperature dependences of thermal diffusivity and thermal conductivity were investigated within the temperature range from 25 to 400 °C. It was found that the thermal diffusivity and thermal conductivity of the annealed alloy are considerably higher than that of the as-cast alloy at temperatures lower than 300 °C. With increasing temperature, due to changes in the microstructure of the as-cast alloy, these differences decrease and finally diminish at 400 °C. The measured eutectic temperature is 522.3 °C and latent heat of melting is 358.3 Jg-1. The findings suggest that the Al–Cu–Si eutectic alloy shows good potential for use in phase change energy storage technologies.Item Enhancing Wastewater Treatment Through Python ANN-Guided Optimization of Photocatalysis with Boron-Doped ZnO Synthesized via Mechanochemical Route(MDPI, 2025) Nedelkovski, Vladan; Radovanović, Milan B.; Medić, Dragana; Stanković, Sonja; Hulka, Iosif; Tanikić, Dejan; Antonijević, MilanThis study explores the enhanced photocatalytic performance of boron-doped zinc oxide (ZnO) nanoparticles synthesized via a scalable mechanochemical route. Utilizing X-ray diffraction (XRD) and scanning electron microscopy with energy-dispersive spectroscopy (SEM-EDS), the structural and morphological properties of these nanoparticles were assessed. Specifically, nanoparticles with 1 wt%, 2.5 wt%, and 5 wt% boron doping were analyzed after calcination at temperatures of 500 °C, 600 °C, and 700 °C. The obtained results indicate that 1 wt% B-ZnO nanoparticles calcined at 700 °C show superior photocatalytic efficiency of 99.94% methyl orange degradation under UVA light—a significant improvement over undoped ZnO. Furthermore, the study introduces a predictive model using the artificial neural network (ANN) technique, developed in Python, which effectively forecasts photocatalytic performance based on experimental conditions with R2 = 0.9810. This could further enhance wastewater treatment processes, such as heterogeneous photocatalysis, through ANN-guided optimization.Item Application of Graphite Electrodes Prepared from Waste Zinc−Carbon Batteries for Electrochemical Detection of Xanthine(MDPI, 2025) Radovanović, Milan B.; Simonović, Ana T.; Petrović Mihajlović, Marija B.; Tasić, Žaklina Z.; Antonijević, Milan M.Waste from zinc−carbon batteries poses a serious environmental protection problem. One of the main problems is also the reliable and rapid determination of some compounds that may be present in food and beverages consumed worldwide. This study addresses these problems and presents a possible solution for the electrochemical detection of xanthine using carbon from spent batteries. Cyclic voltammetry and differential pulse voltammetry are electrochemical methods used for the detection of xanthine. The techniques used demonstrate the mechanism of xanthine oxidation in the tested environment. A linear correlation was found between the oxidation current peaks and the xanthine concentration in the range of 5·10−7 to 1·10−4 M, as well as the values for the limit of detection and the limit of quantification, 7.86·10−8 M and 2.62·10−7 M, respectively. The interference test shows that the electrode obtained from waste Zn-C batteries has good selectivity, which means that the electrode can be used for xanthine determination in the presence of various ions. The data obtained show that carbon sensors from used zinc−carbon batteries can be used to detect xanthine in real samples.Item Electrochemical Detection of Cadmium Using a Bismuth Film Deposited on a Brass Electrode(MDPI, 2025) Radovanović, Milan B.; Petrović Mihajlović, Marija B.; Simonović, Ana T.; Tasić, Žaklina; Antonijević, Milan M.Cadmium is one of the most dangerous pollutants found in the environment, where it exists mainly due to human activities. High cadmium concentrations can cause serious problems, which is why the detection and determination of Cd is one of the most important tasks. Electroanalytical methods provide rapid and accurate results in the detection of cadmium in various solutions. In this study, the possibility of using a bismuth film electrode deposited on a brass surface and electroanalytical techniques for the detection of cadmium is investigated. The bismuth film was deposited on the surface of the brass electrode using a chronoamperometric technique. Cyclic voltammetry and electrochemical impedance spectroscopy were used to characterize the synthesized bismuth film electrode. The current peaks obtained by anodic square-wave stripping voltammetry under optimized conditions showed a linear relationship in the investigated concentration range of cadmium. The study of the interference of different cations (Cr3+, Mn2+, Zn2+, Ca2+, K+, Mg2+ and Na+) showed that the tested cations have no influence on the determination of Cd2+ ions in the investigated solution. This finding provides a good opportunity for the use of the synthesized electrode in real samples.Item Simultaneous determination of serotonin, dopamine, and ascorbic acid at a glassy carbon electrode modified with chitosan-alginate hydrogel and reduced graphene oxide(Elsevier, 2025) Postolović, Katarina S.; Radovanović, Milan B.; Stanić, Zorka D.Detection of biologically active components, such as ascorbic acid, dopamine, and serotonin, is significant from the perspective of biomedicine, particularly in the process of disease diagnosis and in the quality control of commercial pharmaceutical products. In this work, a novel electrochemical sensor was developed by modifying a glassy carbon electrode with a hydrogel composed of a polyelectrolyte complex of alginate and chitosan, along with the addition of electrochemically reduced graphene oxide. This biocompatible sensor was applied for the simultaneous determination of ascorbic acid, dopamine, and serotonin using adsorptive square wave voltammetry. The modified GCE demonstrated an excellent electrochemical response towards the target analytes, thanks to the enhanced adsorption of the analytes on the surface of the electrode, facilitated by favorable interactions between analytes and the modifiers. This approach increased the electrode’s active surface area and ensured excellent electrode response. The sensor exhibited a broad linear range of the anodic current relative to analyte concentration, achieving low detection limits of 0.094 μM, 4.18 nM and 3.23 nM for ascorbic acid, dopamine and serotonin, respectively. Additionally, the proposed sensor exhibited good stability, reproducibility of results, selectivity, as well as effectiveness, in the determination of target biological compounds in real sample matrices.Item Wetting behavior of Sn-Bi solder alloy and composites obtained by powder metallurgy(Fakultet Tehničkih nauka, Kosovska Mitrovica, 2025) Stamenković, Uroš; Marković, Ivana; Nedeljković, Milan; Božinović, KristinaThis study examined the wetting behavior of solders composed of tin-bismuth (SnBi) alloys and their composites. To produce the SnBi12 (wt. %) alloy, pure powders of tin (Sn) and bismuth (Bi) were used. After that, the composites were produced by adding 0.2 wt.% of graphite (C) and boron carbide (B4C) to the SnBi12 alloy. The alloys and composites were fabricated using a powder metallurgy technique. Initially, the powders were weighed in specific ratios to create the SnBi12 matrix powder. After this, 0.2 wt.% of C and B4C were added to the matrix powder. The mixing was done using a three-axis mixer at a speed of 50 rpm for 4 hours. The mixed powders were then mechanically stirred in a ball mill at a speed of 150 rpm for 2 hours. Following this, the powders were compacted with a hydraulic press, and the samples were sintered in an inert argon atmosphere at a temperature of 185 °C for 3 hours. For the wetting behavior investigation, the copper plates were polished and cleaned in acetone. Small samples weighing 0.1 grams were taken from the sintered samples and placed on copper plates along with 0.02 grams of flux RMA218. These copper plates were then heated to 250 °C for 20 seconds to initiate the soldering. After cooling, the solders were cleaned with acetone, photographed, and cut to examine their cross-sections under an optical microscope. The contact angle and spreading area were measured using ImageJ software. The results indicate that the pure tin sample exhibited the highest wetting angle. The addition of bismuth to form the tin-bismuth alloy reduced the wetting angle by approximately 20%. Furthermore, when reinforcements of carbon (C) and boron carbide (B4C) were added, the wetting angles increased slightly but remained lower than that of the pure tin sample. The surface area values mirrored the trends observed in the wetting angles: as the wetting angles decreased, the surface areas increased, and vice versa.Item Melting temperatures and thermal properties of Sn-Bi alloys and composites(Fakultet Tehničkih nauka, Kosovska Mitrovica, 2025) Stamenković, Uroš; Marković, Ivana; Manasijević, Dragan; Ćosović, Vladan; Gorgievski, Milan; Kovačević, Avram; Nedeljković, Milan; Minić, DuškoThis study investigates the melting temperatures and thermal properties of tin-bismuth (Sn-Bi) alloys and their composites. The investigation involved the preparation of pure tin, two alloys (SnBi12 and SnBi21, by weight percentage), and two composites (SnBi12 + 0.2 wt.% Cu and SnBi12 + 0.2 wt.% C) through casting. The pure metals were melted in a graphite crucible at 400 °C for 20 minutes, followed by mechanical stirring. During stirring, 0.2 wt.% of pure carbon powder (with a particle size of less than 45 µm) and pure copper powder (also with a particle size of less than 45 µm) were added separately to the SnBi12 melt to create the two different composites. After melting and stirring, the mixture was cast in a steel mold. Samples were extracted from the cast ingots for differential thermal analysis (DTA) to determine the melting temperatures of the investigated samples. Additionally, samples were prepared to assess thermal diffusivity, thermal conductivity, and specific heat using the Xenon flash method at room temperature. The DTA analysis revealed that the melting temperature was the highest for the pure tin sample. The addition of bismuth reduced the melting temperature from 237.43 °C for pure tin to 222.59 °C for SnBi12 and 211.35 °C for SnBi21. The melting temperatures of the SnBi12 + Cu and SnBi12 + C composites were nearly identical to that of the SnBi12 alloy, indicating that the dispersed particles did not influence the melting temperature. Furthermore, thermal diffusivity, thermal conductivity, and specific heat values were lower for the alloys compared to those of the pure tin sample. The composites also exhibited lower thermal diffusivity and thermal conductivity values compared to the SnBi12 alloy. In conclusion, bismuth affects both the melting temperature and the thermal properties of Sn-Bi alloys, while Sn-Bi composites influence thermal properties without affecting the melting temperature of Sn-Bi alloys.Item Chemometric Evaluation of 16 Priority PAHs in Soil and Roots of Syringa vulgaris and Ficus carica from the Bor Region (Serbia): An Insight into the Natural Plant Potential for Soil Phytomonitoring and Phytoremediation(MDPI, 2025) Papludis, Aleksandra D.; Alagić, Slađana Č.; Milić, Snežana M.; Nikolić, Jelena S.; Jevtović, Snežana Č.; Stankov Jovanović, Vesna P.; Stojanović, Gordana S.; Gianniantonio PetruzzelliThe soil phytomonitoring and phytostabilization potential of Syringa vulgaris and Ficus carica was evaluated regarding 16 priority polycyclic aromatic hydrocarbons (PAHs) using a chemometric approach and the calculation of bioconcentration factors (BCFs) for each individual PAH in plants’ roots from each selected location in the Bor region. PAHs in roots and the corresponding soils were analyzed using the QuEChERS (Quick, Effective, Cheap, Easy, Rugged, Safe) method with some new modifications, gas chromatography/mass spectrometry, Pearson’s correlation study, hierarchical cluster analysis, and BCFs. Several central conclusions are as follows: Each plant species developed its own specific capability for PAH management, and root concentrations ranged from not detected (for several compounds) to 5592 μg/kg (for fluorene in S. vulgaris). In some cases, especially regarding benzo(a)pyrene and chrysene, both plants had a similar tactic—the total avoidance of assimilation (probably due to their high toxicity). Both plants retained significant quantities of different PAHs in their roots (many calculated BCFs were higher than 1 or were even extremely high), which recommends them for PAH phytostabilization (especially fluorene, benzo(b)fluoranthene, and benzo(k)fluoranthene). In soil monitoring, neither of the plants are helpful because their roots do not reflect the actual situation found in soil. Finally, the analysis of the corresponding soils provided useful monitoring information.Item Change in pH and conductivity during the rinsing and the biosorption of copper ions onto pumpkin peel(University of Zenica, Faculty of Metallurgy and Technology, 2025) Marković, Marina; Gorgievski, Milan; Marković, Miljan; Grekulović, Vesna; Štrbac, Nada; Zdravković, Milica; Božinović, KristinaThe changes in pH and conductivity during the rinsing of the pumpkin peel, and the biosorption of Cu2+ ions, were the subject of this work. The obtained data showed that the pH value of the solutions increased during the rinsing of the biosorbent, as a result of the transfer of H+ ions from the aqueous phase into the structure of the pumpkin peel. An increase in the conductivity value was observed in the initial period of rinsing the pumpkin peel, followed by a decrease. The increase in conductivity in the initial phase contributed to the self-leaching of the alkali and alkaline earth metal ions from the structure of the pumpkin peel, which were transferred into the aqueous phase. The further decrease in conductivity is a result of the dilution of the aqueous phase. The pH value decreased during the biosorption of Cu2+ ions, as hydrogen ions were transferred from the pumpkin peel structure into the solution, and then exchanged with Cu2+ ions. The conductivity value increased during the biosorption process, with a rapid increase in the initial period of 5 minutes, due to the transfer of alkali and alkaline earth metal ions into the solution.Item Characterization of electrode materials from spent batteries in the process of recovering valuable metals(University of Belgrade, Technical Faculty in Bor, 2025) Medić, Dragana; Nujkić, Maja; Tasić, Žaklina; Nedelkovski, Vladan; Đorđievski, Stefan; Alagić, Slađana; Milić, SnežanaThe chemical and phase analysis of electrode materials from spent batteries is essential for identifying recyclable components and optimizing metal recovery processes. In this study, the electrode material from a spent cell of an unknown manufacturer was analyzed using inductively coupled plasma mass spectrometry (ICP-MS) and powder X-ray diffraction (XRD). XRD results revealed that the anode material consists of three crystalline phases: NiO, LaCoO3, and CeO₂, while the cathode material contains Ni(OH)₂ and Ni. ICP-MS analysis confirmed the presence of lanthanides in the anode material. Given that lanthanide deposits are concentrated in only a few countries, their recovery from spent batteries presents an opportunity for nations without natural reserves to secure their supply through recycling. This study highlights the potential for sustainable resource management by recovering metals from electronic waste.Item Raspberry and blackberry grown in Serbia from the aspect of the green agenda(Naučno-stručno Društvo za zaštitu životne sredine Srbije ECOLOGICA, 2024) Zdravković, Milica; Grekulović, Vesna; Štrbac, Nada; Zdravković, Bojan; Gorgievski, Milan; Marković, Miljan; Marković, MarinaSerbia is one of the leading countries in the world in terms of raspberry and blackberry production. Production is focused on the cultivation of raspberries and blackberries for the purpose of the fruit selling, so large amounts of leaves of these two plants remain unused on plantations or are burned. In tradicional medicine, the healing effects of raspberry leaves and blackberry leaves are known, but due to the large production, it is impossible to use all the leaves for these purposes. Newer research indicates numerous possibilities of application of raspberry leaves and blackberry leaves. An important aspect is the use of raspberries and blackberries that grow near the mine. In addition to being used in medicine and pharmacy, extracts can be used as metal corrosion inhibitors. Depleted plant mass that can be used for biosorption, as a binding agent and starting component of cellulose production. Obtaining the extract instead of burning the leaves fulfills the first condition of the Green Agenda, which is decarbonization and reduction of industrial emissions. Environmental pollution is reduced with a focus on air quality. Better energy efficiency is achieved by an adequate selection of extragens. The circular economy is achieved by a system in which production resources (fruit and leaves) are encouraged, and waste, waste emission and energy outflow are significantly reduced. In addition to encouraging the economy and sustainable plant food systems that are characteristic of the Western Balkans, protection and investment in ecosystems is achieved.Item Malina i kupina gajene u Srbiji sa aspekta Zelene agende(Naučno-stručno Društvo za zaštitu životne sredine Srbije ECOLOGICA, 2024) Zdravković, Milica; Grekulović, Vesna; Štrbac, Nada; Zdravković, Bojan; Gorgievski, Milan; Marković, Miljan; Marković, MarinaSrbija je jedna od vodećih zemalja u svetu po proizvodnji maline i kupine. Proizvodnja je usmerena na gajenje maline i kupine radi prodaje ploda, pa velike količine lista ove dve biljke ostaju neiskorišćene na plantažama ili bivaju spaljene. U narodnoj medicini je poznato lekovito dejstvo lista maline i lista kupine, ali je zbog velike proizvodnje nemoguće iskorititi svu količinu listova u ove svrhe. Novija istraživanja ukazuju na brojne mogućnosti primene lista maline i lista kupine. Važan aspekt predstavlja upotreba maline i kupine koja raste u blizini rudnika. Pored upotrebe u medicini i farmaciji ekstrakti se mogu koristiti kao inhibitori korozije metala. Osiromašena biljna masa se može primeniti za biosorpciju, kao vezivno sredstvo i polazna komponenta proizvodnje celuloze. Dobijanjem ekstrakta umesto spaljivanja listova ispunjava se prvi uslov Zelene agende, a to je dekarbonizacija i smanjenje industrijskih emisija. Smanjuje se zagađenje životne sredine sa fokusom na kvalitet vazduha. Adekvatnim izborom ekstragensa postiže se bolja energetska efikasnost. Cirkularna ekonomija se postiže sistemom u okviru kojeg se podstiču proizvodni resursi (plod i list), a otpad, emisija otpada i energetski odliv bitno umanjuju. Pored podsticanja privrede i održivih prehrambenih sistema biljaka koje su karakteristične za Zapadni Balkan, postiže se zaštita i investiranje u ekosisteme.Item Application of AI in environmental protection: corrosion and biosorption(Naučno-stručno Društvo za zaštitu životne sredine Srbije ECOLOGICA, 2025) Zdravković, Milica; Marković, Miljan; Marković, Marina; Grekulović, Vesna; Gorgievski, Milan; Štrbac, Nada; Božinović, KristinaArtificial intelligence (AI) plays an important role in the field of scientific research. This paper aims to review the application of AI in corrosion and biosorption. The use of AI can advance the research process in terms of prediction, environmental and cost management, optimization and determination of the influence of parameters. Corrosion is a highly complex process that depends on many factors. Studying the interaction of these factors using AI enables better corrosion control. By applying AI, it is possible to determine the diverse influence of factors under real conditions using the database of numerous researches. In addition to the prevention and monitoring of corrosion and biosorption processes, it is important to focus the application of AI on environmentally friendly methods and chemicals. In this way, it is possible to identify compounds and materials of natural origin that can serve as substitutes for toxic compounds for corrosion protection or heavy metal removal. The importance of using non-destructive methods and monitoring data in real time is particularly emphasized, in order to avoid statistical errors. Optimization with the RSM method for corrosion and biosorption processes is widely used, determining process parameters where the best effect of corrosion protection and biosorption is achieved.
