Melon (Cucumismelo) and Groundnut (Arachishypogaea) peel extracts as corrosion inhibitors for mild steel in hydrochloric acid solution

Abstract

The corrosion inhibition of mild steel in 2M hydrochloric acid solution by Melon (Cucumismelo)(MPE) and Groundnut (Arachishypohaea) peel extracts (GPE) at room temperature has been investigated using weight loss method. Inhibition efficiencies of 94.40% and 92.64% for2M HCl concentration was observed for GPE and MPE respectively. Generally, the weight loss of the coupons decreases at different concentrations of HCl solutions while the inhibition efficiencies of the inhibitors (MPE and GPE) increased with increasing inhibitor concentrations.
