Corrosion Inhibition Of Mild Steel In Solution Of Acid And Alkaline Media Using Aloe Vera Gel
ABSTRACT
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.
