摘要:The effect of propolis extract on the corrosion inhibition of Al in acid medium was studied. The inhibition studies were carried out on Al in 1 M HCl with the propolis extract using Electrochemical Impedance Spectroscopy (EIS) . Parameters, such as concentration of the inhibitor, temperature were varied and optimized. The results revealed that the increase of the temperature and concentration of acid can decrease the performance of the inhibitor. Thermodynamic parameters demonstrate that the physisorption of the inhibitor molecules on Al surface obeys Langmuir isotherm.
