Abstract

The effect of 1H-benzotriazole (BTAH) with ppm (part per million) grade concentrations on copper corrosion in aerated 3 wt. % NaCl solution is studied using chemical method (weight loss) and electrochemical methods (Potentiodynamic Polarization and Electrochemical Impedance Spectroscopy (EIS)). The present study confirm that the BTAH acts as a mixed-type inhibitor of copper corrosion in 3 wt. % NaCl. The optimum inhibition efficiency is at 30 ppm of BTAH. The surface characterization is performed using Scanning Electron Microscopy (SEM) to confirm the adsorption of the inhibitor molecules after 21 days of immersion time in aerated 3 wt. % NaCl. The results obtained from different techniques used in this research are in very good agreement and revealed that the BTAH is a very good inhibitor of copper corrosion in sodium chloride medium. Computer Simulation techniques confirm that the BTAH molecules adsorbed on the Cu (110) Surface.
