Abstract

Corrosion inhibition of Schiff base (AMPNSA) and their metal chelates [Ti (IV), Zr (IV), Cd (II), and Hg (II)] were evaluated using Weight Loss Method in 0.1M, 0.01M and 0.001M (HCl, HNO3 and H2SO4) in various Mineral acid medium solutions for copper metal wire. It was found that Schiff base and their metal complexes promising inhibitory action against corrosion of copper metal. Thus inhibition efficiency was obtained of various Schiff base and their metal chelates. Ligand and its complexes showed high surface activity. Increasing the surface activity of the inhibitor solutions is accompanied by increase in corrosion inhibition efficiency. The purpose of this study is to understand the inhibitor behaviour of specific Ligand and their metal complexes against copper metal corrosion and their adsorption mechanism on the metal surface.
