| Abstract: | The objective of this paper was to investigate the efficiency of arylsubstituted benzimidazoles for corrosion inhibition of copper in 0 5 mol/L hydrochloric acid solution. Corrosion was studied using weight loss measurement and SEM. Activation energy was obtained by measureing the concentration of the inhibitory efficiency. The adsorptive behavior of the arylsubstituted benzimidazoles on the copper surface follows a Freudlich type isotherm. |
