Corrosion processes results to numerous failures and eventual losses in industries. These failures imposed by corrosion effects can be reduced through the use of inhibitors. The aqueous extracts of Aloe Vera gel was investigated as a novel corrosion inhibitor for mild steel in both acid and alkaline media using gravimetric method. Corrosion rate, inhibition efficiency, degree of surface coverage, adsorption mechanism, free energy and thermodynamic parameters were determined through the performance of the corrosion inhibition efficiency obtain in both media. The adsorption on mild steel surface agrees with the Langmuir adsorption isotherm model, the negative Gibbs G and equilibrium constant K values indicated the spontaneity, physisorption, stability of the adsorption and the exothermic nature on mild steel, suggesting that Aloe vera gel is a common inhibitor for corrosion for Hydrochloric Acid (HCl) and Sodium Hydroxide (NaOH) media and can be used as a replacement to toxic and non-bio gradable inhibitors.
