  • Abstract

    The anticorrosive effect of the aqueous extract of Launaea resedifolia on the corrosion of carbon steel X52 in 1.0 M H2SO4 solution was investigated electrochemically and by weight loss experiments at room temperature. The percentage inhibition increased with the increase of the inhibitor concentration. The studies reveal that the plant extract act as a good inhibitor. Tafel polarization method indicated that the plant extract behaves as mixed mode inhibitor. The inhibition was assumed to occur via adsorption of the inhibitor molecules on the metal surface.
