This research investigated the inhibition behavior of Spondias mombin leaf (SML) extracts in 0.1 M HCl solution on mild steel at various concentrations and temperatures. The result reveals that the inhibition efficiency of the extract on the mild steel sheet increases with increasing concentration of the extract and decreases with increase in temperature. Therefore, the adsorption mechanism of the extract on the mild steel surface is physical. Calculated Correlation Coefficient (R2) values show that the process follows a Freundlich adsorption isotherm. The proposed temperature coefficient equation of adsorption mechanism was found to be appropriate.
