Abstract

The article presents the results of the study of the electrochemical behavior of copper during oxidation in a 0.5 mol/dm3 NaCl solution in the absence and presence of pine cone macerate of different concentrations. The electrochemical behavior of copper was investigated using the cyclic voltammetry method and the potentiostatic method. The results of cyclic voltammetry show 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 0.5 mV vs. SCE for 100 s and at 25oC. Potentiostatic curves show that the steady-state currents decrease with increasing concentration of macerate in the electrolyte. Microscopic images confirm that a protective layer has formed on the copper surface in the presence of the pine cone macerate, which prevents the corrosion process.
