INFLUENCE OF GOKHRU LEAVES EXTRACT ON CORROSION INHIBITION OF ALUMINIUM IN ACIDIC MEDIUM

Abstract

Now a days, industries are facing the problem of corrosion of metals and to control it, is a challenging job in industrial revolution. The plant Gokhru (Tribulus terrestris) can be used as eco-friendly corrosion inhibitor for aluminium in aggressive industrial environment. The corrosion inhibition efficacy of alcoholic extract of leaves of plant Gokhru for aluminium in sulphuric acid has been studied in relation to the concentration of inhibitor, concentration of acid and immersion time by mass loss method. Inhibition efficiency increases with inhibitor concentration and immersion time but decreases with increase of acid strength.
