The Inhibition of Copper Corrosion in Acid Media

The aim of this work is to study the inhibiting efficiency of secondary and tertiary amines on copper corrosion in acid solutions. The investigation was performed by electrochemical methods as well as by gravimetric method in hydrochloric and sulphuric acid. The results obtained have been compared with the efficiency of commercial inhibitor for copper. The results of the investigation have shown that secondary amine has better inhibiting properties than tertiary amine.The inhibiting characteristics of N-5-bromo-2-furfuryl-p-toluidine in sulphuric acid are better than those of commercial inhibitor in the same conditions.
