Abstract :
The inhibitive action of rhizome extracts of Acoruscalamus on mild steel corrosion in 0.5 N H2SO4 solution was studied using weight loss method, potentiodynamic polarization and EIS measurements. The results obtained indicate that the extracts functioned as good inhibitors in H2SO4 solution. Inhibition efficiency was found to increase with extract concentration. The adsorption of constituents in the plant extract on the surface of the metal is proposed for the inhibition behavior.
