An aqueous extract of Amomum sabulatum seeds was evaluated for anticorrosive effects on mild steel in the presence of HCl. Weight loss measurements were taken to determine the corrosion rate and inhibition efficiency at various concentrations. With the increasing concentrations of plant extract, the results showed an improvement in inhibition efficiency and a decrease in corrosion rate. In the presence of 1500 ppm concentration of plant extract, it has an inhibition efficiency of 82.08 % at 303 K. The scanning electron microscope was used to examine the surface, which proves that while the extract was there, a protective layer formed on the metal surface.
Key words: Inhibition efficiency / Amomum sabulatum seeds / SEM / weight loss measurements / adsorption isotherm, corrosion
