KEYWORDS: CORROSION INHIBITION OF ALUMINUM USING EXTRACT OF BRYOPHLLUM PINNATUM IN ACIDIC AND ALKALINE MEDIA

ABSTRACT:

The inhibition efficiency of Bryophllum pinnatum on corrosion of aluminum coupons was investigated in 0.5M NaOH and HCl solutions using weight loss method. The corrosion rate of aluminum decreased with an increase in inhibitor concentration, but decrease with increase temperature. The decrease in inhibitor efficiency with increase temperature suggests that inhibiting molecules were physically adsorbed onto the corroding metal surface.
