The inhibition effect of the new Schiff base, namely 2,2′‐[bis‐<i>N</i>(4‐choloro benzaldimin)]‐1,1′‐dithio against mild steel corrosion

Abstract

Abstract 2,2′‐[bis‐ N (4‐choloro benzaldimin)]‐1,1′‐dithio has been synthesized and its inhibiting action on the corrosion of mild steel in 0.5 M sulfuric acid was investigated by various corrosion monitoring techniques, such as weight loss and potentiodynamic polarization techniques. The experimental results suggest that this compound is a good corrosion inhibitor for mild steel and the inhibition efficiency increases with the increase in inhibitor concentration. This organic compound is a mixed type inhibitor in the acid solution, and its adsorption on the mild steel surface is also found to obey the Langmuir adsorption isotherm.
