Abstract: The corrosion Inhibitive effect of Coconut (Cocos nucifera linn) juice on the acid corrosion of aluminium in 1M HCl solution was studied by a weight loss technique which is regarded as the best method for this analysis. The analyses were carried out using 5-30ml of the Cocos nucifera linn. Aluminum sheets of purity 99.8% were used in this study. Each sheet was 0.12cm thick and was cut into square like shaped coupons of dimension 4 cm x 5 cm. However, surface treatment of the coupon involved degreasing in absolute ethanol and drying in acetone. The pre-weighted aluminum coupons were totally immersed in a beaker containing the corroding acidic medium of various concentration of the inhibitor at the time intervals of 1-5 hours. The inhibitor exhibited highest inhibition efficiency of 84.0% at the highest inhibitor concentration of 60% v/v. The corrosion rate was found to decrease. It was found that the extracts of Cocos nucifera inhibited the corrosion of aluminium in this acid medium. The inhibitor (coconut water) efficiency increased with increasing concentration of the Cocos nucifera juice at 300C. This research showed that coconut juice possesses inhibiting properties for reducing the corrosion of aluminium in the1M HCl.
