Abstract
The inhibition of corrosion of copper in hydrochloric acid and tetraoxosulphate (VI) acid Solutions by Aloe Vera gel has been evaluated by the weight loss method. Inhibition efficiency increased with increase in concentration of the inhibitor system. As the temperature increased the inhibition efficiency decreased. The process follows first order kinetics, and obeys Langmuir adsorption Isotherm. The composition of the active principle of Aloe Vera gel is given.
