The leaves of Vitis vinifera has been tried as a green corrosion inhibitor for mild steel in 1 M HCl. Its inhibitive performance was studied using mass loss method and Electrochemical methods namely potentiodynamic polarization and AC impedance method. The performance of the inhibitor at different time periods, different concentrations of the inhibitor and at various temperatures has been studied. The studies revealed that Vitis vinifera act as a good inhibitor in 1M HCl medium and the maximum efficiency was 97.31 More »»

The inhibition efficiency of acid extract of leaves of Citrus aurantiifolia [CAL] plant on the corrosion of mild steel in 1 M HCl was investigated by weight loss measurements and electrochemical studies. The corrosion rate of mild steel and the inhibition efficiencies of the extract were calculated. The results obtained show that the extract could serve as an effective inhibitor for the corrosion of mild steel in HCl media. Inhibition was found to increase with increasing concentration of the plant extract. More »»

Abstract Large extent of mild steel corrosion occurs during acid pickling and surface cleaning. Various synthetic chemicals have been studied as corrosion inhibitors and reported. But pure synthetic chemicals are costly. Some of them are toxic and their disposal creates pollution problems. In the present study the acid extract of Ricinus Communis leaves have been investigated as a cheap and eco-friendly corrosion inhibitor for mild steel in 1M HCl medium by weight loss and polarization techniques.
