Solid waste as environmental benign corrosion inhibitors in acid medium

Abstract

The inhibitive properties of solid waste (Genus Musa, Genus Saccharum and Citrullus Lanatus) on the corrosion of mild steel strip in 1M HCl were investigated using weight loss technique. These materials are considered as waste and constitute nuisance to the environment as there is no meaningful uses of them. Inhibition efficiency of 69.60%, 68.41%, and 58.15% at 10% v/v of extracts concentration for 72 hours exposed time for Genus saccharum, Citrullus lanatus and Genus musa, respectively, were achieved. Adsorptions of the inhibitors molecules on mild steel strip surfaces were consistent with Langmuir adsorption isotherm.
