Abstract
The use of plant extracts to inhibit copper corrosion is the subject of numerous scientific studies. This paper presents the results of research the electrochemical behavior of copper during oxidation in a 0.5 mol/dm3 NaCl solution in the absence and presence of nettle extract (NE) in different concentrations. The electrochemical behavior of copper was investigated using the cyclic voltammetry and the potentiostatic method. The results of cyclic voltammetry showed that three current peaks appear on the anodic polarization curves, which correspond to the formation of copper chloride and copper oxide. Potentiostatic polarization was performed at 0 mV vs. SCE during 100 s at 25 oC. The potentiostatic curves indicate that the stationary currents decrease with increasing extract concentration in the electrolyte. Microphotographs confirmed that in the presence of NE, a protective layer was formed on the copper surface, which prevents the corrosion process.
