Abstract

Ethanol extracts of Nymphaeaceae and Aloe barbadenis were used to evaluate the corrosion inhibition of mild steel in 1M H2SO4 by adsorption isotherm experiments using the gravimetric method. A. barbadenis demonstrated a greater percentage of inhibition efficiency (%IE), and it was observed that for an increase in immersion period and inhibitor concentration, the corrosion rate of mild steel coupons decreases with the plant extracts presence (0.5–1.5 w/v%). The result has reportedly shown an increase in the inhibitor's inhibitory efficacy of up to 343K, pointing to extract adsorption onto the surface of mild steel. The Langmuir and Temkin adsorption isotherm were found to be followed by the adsorption on mild steel.
