Abstract: The inhibition of the corrosion of mild steel 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 temperature. The results obtained show that Aloe vera gel could serve as an effective and non-toxic inhibitor of the corrosion of mild steel in hydrochloric acid solution.

Keywords: Corrosion inhibition; mild steel; weight loss; Aloe vera; hydrochloric acid.
