Corrosion Inhibition Studies at Iron Surface in Acetic Acid Solutions by Aqueous Extract of Fenugreek Leaves

Alka Singh and S. Kalpana

Gravimetric method was used to study the effect of aqueous extract of Fenugreek leaves (AEFL) on the corrosion of iron in CH3COOH solutions at different temperatures. The inhibition efficiency of AEFL increases with increase in inhibitor concentration and the adsorption of AEFL on iron surface obeys the Langmuir adsorption isotherm. The aqueous extract of Fenugreek leaves is observed as good potential corrosion inhibitor in acetic acid solutions at experimental conditions.
