Abstract
Potentiodynamic polarization measurements and electrochemical impedance spectroscopy were used to study the inhibition effect of Citrus aurantiifolia leaves on the corrosion of mild steel in 1.0 M HCl and 0.5 M H2SO4 solutions. The results obtained show that the inhibition was found to increase with increasing concentrations of the plant extract. Polarization curves revealed that the inhibitor acts as mixed type inhibitor and inhibition efficiency follows the order: HCl> H2SO4.
