Abstract
The influence of blackberry leaf extract (BLE) on copper corrosion in 0.5 M NaCl solution was investigated. The extract was made as evaporated blackberry leaf water extract. The cyclic voltammetry (CV) was performed in a blank solution and a solution with the addition of 15 g/L BLE. Surface characterization was performed using scanning electron microscope with energy dispersive X-ray spectroscopy (SEM-EDS). The copper surface characterization was performed on copper specimens after 1 day of immersion in a blank solution and in a solution with the addition of 15 g/L BLE. Three anodic current peaks and two cathodic current peaks were observed on the cyclic voltammogram without the addition of BLE. The CV results show that there was a reduction of anodic and cathodic current peaks in the presence of BLE, which clearly confirms that BLE reduced the amount of corrosion products. SEM-EDS results confirm that a smaller amount of copper oxide and chloride occurs on the copper surface in the presence of BLE in relation to the copper surface in the blank solution. The results show that BLE acts as a good copper corrosion inhibitor in a chloride environment.
