Effect of Acid Extract of Different Parts of Tephrosia Purpuria on Corrosion of Iron in Acid

Akshay Kumar Sakerwal and V. K. Swami

Corrosion of iron in 1 N HNO3 solution was studied by mass loss method in absence and presence of the acid extract of Tephrosia purpuria plant from the change in this electrochemical parameter. It was concluded that the inhibition increased with increase in the concentration of additive. This work was aimed at developing cheap, eco-friendly and biodegradable acid corrosion inhibitors.
