Alkaloid and nonalkaloids extracts of Cnidoscolus aconitifolius stem is reported as corrosion inhibitor of mild steel in 2.0 M H2SO4. Conventional weight loss measurements and Tafel polarization technique are employed to study the effect on mild steel corrosion in H2SO4 solutions. The weight loss result revealed that both plant extracts are excellent corrosion inhibitors. Electrochemical polarization data revealed mixed mode of inhibition. The increase in %IE with change in concentration of the extracts suggests the strong adsorption of active molecules leading to the formation of a protective layer on the mild steel surface. It was found that adsorption of both stem extracts followed Langmuir adsorption isotherm model.
