ABSTRACT

Abstract: Oxystelma esculentum leaves inhibition effects on the corrosion of steel in 0.5M H2SO4 solution were investigated using polarization and electrochemical impendence techniques. The results revealed that Oxystelma esculentum leaves acts as a corrosion inhibitor in 0.5M H2SO4 solution. The inhibition efficiency increased with an increase in inhibitor concentration. The inhibition is attributed to adsorption of the inhibitor on the steel surface.
