    MILD STEEL CORROSION INHIBITION IN ACIDIC MEDIA USING SARCOCEPHALUS LATIFOLIUS LEAVES EXTRACT
    (university of el oued/جامعة الوادي, 2023-03-29) Iorhuna, Fater; Ayuba, Abdullahi Muhammad
    At temperatures between 303K and 323K, three different concentrations of the methanol extract from Sarcocephalus latifolius were utilized to inhibit the corrosi on of mild steel coupons in a 0.9M HCl solution. The plant extract adhered to the surface of mild steel metal under the investigated conditions, according to surface characterization techniques including SEM and FT IR. It has been proven through weight los s trials in this work that the plant extract's ability to suppress growth improves with both an increase in its concentration and a decrease in temperature. The corrosion and inhibition processes were presented as being viable and spontaneous using thermod ynamic para meters. Additionally, it was determined that the inhibitory process followed first order kinetics, with half life values rising as plant extract concentration did. Calculated activation energy values and isotherm characteristics demonstrated tha t the proce ss adheres to the physical adsorption mechanism.
