Electrochemical Linear Polarization Studies of Amodiaquine Drug as a Corrosion Inhibitor for Mild Steel in 0.1M HCL Solution

I. A. Akpan, N. O. Offiong

Abstract


The effect of amodiaquine on corrosion of mild steel in hydrochloric acid was investigated by linear polarization resistance (LPR) electrochemical method. The results indicated that corrosion inhibition efficiency and degree of surface coverage were increased with rise in the concentration of amodiaquine. The inhibitor followed monolayer chemisorption since it obeyed the Langmuir adsorption isotherm.

Keywords: linear polarization resistance (LPR), amodiaquine drug, corrosion inhibitor, mild steel, HCl
