Abstract
 

The inhibition of the corrosion of aluminium in hydrochloric acid solutions by Aloe vera gel has been studied using weight loss method. Inhibition was found to increase with increasing inhibitor concentration and decreasing temperature. The results obtained show that Aloe vera gel could serve as an effective and non-toxic inhibitor of the corrosion of aluminium in hydrochloric acid media.

Keywords: Corrosion inhibition, aluminium, weight loss, Aloe vera
