dc.description.abstractThis study investigates the influence of Prosopis Africana pod extract (PAPE) on corrosion behavior of mild steel in 1.0 M HCl. The Prosopis African Seed Extract (PASE) was previously characterized as a green corrosion inhibitor without considering its pod, which often constitutes environmental pollution. The PAPE solution was administered in varying concentrations of 0.0 g/ml to 10.0 g/ml as a green inhibitor of mild steel in 1M Hydrochloric (HCl) medium at room temperature using gravimetric, gasometric and electrochemical (Tafel Polarization) techniques. The volume of hydrogen evolution determined with gasometric process decreases as the concentration of the extract increases. The gravimetric technique recorded the highest inhibition efficiency (IE%) of 97.14% with a 1.0g/l concentration of PAPE. The electrochemical measurements of the corrosion current density (ICorr) decreased as the concentration of PAPE increased, with a maximum IE% of 80.59% (PAPE) at 1.0g/l recorded. Generally, IE% increases with the concentration of the extract. The decrease in the corrosion rate is caused by the intensified obstructive mechanism in the coupon surfaces instigated by the pod extract's adsorption. Hence, the extract from Prosopis Africana Pod is equally suitable as a green inhibitor for corrosion.
