Mimusops Elengi Linn Plant Extract as an Efficient Green Corrosion Inhibitor for Mild Steel in Acidic Environment

Corrosion inhibition of mild steel in 1 N HCl by Mimusops Elengi Linn (MEL) leaves extract was studied using Weight Loss Method, Potentiodynamic Polarization and Electrochemical Impedance Spectroscopy (EIS) measurements techniques at room temperature. It was found that the inhibition efficiency of the MEL extract obtained from impedance and Polarization measurements was in a good agreement and increases with increasing concentration of MEL extract. The inhibition was found to be highest (97.63%) at a concentration 20ppm of the extract. The results obtained showed that the MEL extract could serve as an effective inhibitor for the corrosion of mild steel in acid media.
