JATROPHA GOSSYFOLIA- A GREEN INHIBITOR ACT AS ANTICORROSIVE AGENT ON CARBON STEEL

Abstract

A new and eco friendly alternative green inhibitor is proposed for anticorrosion in carbon steel instead of commonly adopted Synthetic counterpart. Adsorption behaviour and Inhibition efficiency of the inhibitor on Carbon steel surface investigated by Weight loss method. Observed result reveals that the percentage of inhibition efficiency (95.99%) increased with increase of concentration (0-1000ppm) and the efficiency decreased (88%) when the temperature rose from 303k to 333k. Adsorption of the inhibitor on the carbon steel surface follows Langmuir isotherm (R2= 0.9973) and the values of activation energy suggested that the adsorption of inhibitor is physisorption. The image of Scanning electron microscope and the characterization studies of corrosion products revealed the adsorption behavior of active organic compounds of the extract on the interface metal/solution. Thus may concluded that the applicability of the proposed green inhibitor on carbon steel behave more efficient anticorrosion agent.
