dc.description.abstractThe inhibiting effect of leaf extracts of Hyppocratea pallens planhc.ex oliv on the corrosion of mild steel in 1.0 M HCl and 0.5 M H2SO4 solutions has been investigated by weight loss, electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization (PDP) techniques. The effect of temperature on the corrosion and inhibition processes was studied in the temperature range 303-333K. The presence of this plant extract reduced considerably the corrosion rate of mild steel in acidic media and the corrosion inhibition efficiency increased with extract concentration up to 1000 mgL-1. The results suggest that the extract inhibited the corrosion reaction via adsorption of the organic matter on the metal surface, following the Langmuir isotherm and inhibited both the anodic and cathodic partial reactions.
