Mild Steel Corrosion Inhibition by Cucurbitamaxima Plant Extract in Hyddrochloric Acid Solution


The inhibitive action of PCM (peel of Cucurbita maxima) on mild steel corrosion in 1N HCl was studied using weight loss method and FT IR techniques. The calculated results of corrosion rates of steel and the inhibition efficiency of plant extract show that the extract functions as a good corrosion inhibitor and IE increased with extract concentration. Maximum IE of 93 % was obtained at 2 % v/v concentration of the plant extract. Temperature studies revealed an increase in IE with rise in temperature. The adsorption of PCM extract was found to follow Langmuir's adsorption model at all concentrations and temperatures studied.
