Inhibition Effect of Cajanus Cajan Leaves Extract on the Corrosion of Mild Steel in 1 M HCl Solution
Abstract
In the present work, the corrosion inhibition property of Cajanus cajan leaves extract (CCLE) was investigated as green inhibitor for the corrosion of the surface of mild steel in 1M HCl by weight loss and SEM analysis. The adsorption of the extracts onto mild steel surface followed Langmuir adsorption isotherm. The mechanism of physical adsorption has been proposed based on the trend of inhibition efficiency with temperature. Morphological study of the mild steel surface was undertaken by scanning electron microscope (SEM).
Keywords: Adsorption, Mild steel, Inhibitor, Hydrochloric acid.
