CORROSION INHIBITION OF Caesalpinia coriaria (DIVI-DIVI) PODS EXTRACT ON MILD STEEL IN 1M SOLUTIONS OF HCL AND H2SO4
Abstract
The Corrosion inhibition effect of antioxidants from Caesalpinia coriaria (Divi-Divi) pods extract on Mild Steel in 1M HCL and H2SO4 has been investigated extensively by weight loss. The effect of media (acids) to extract on the corrosion inhibition of Mild Steel at the room temperature of 303K was satisfactorily analysed. The results obtained indicated that Caesalpinia coriaria extract contains antioxidants and acted as effective inhibitor in the acid media, having inhibition efficiencies of 1.44% at 0.1g/l and 9.96 at 0.2g/l of inhibitor concentration in HCl and H2SO4 respectively. The inhibition efficiency of the antioxidants from the extract increases with the increase in concentrations but decreases with the increase in temperature. The inhibitor achieves its inhibition through physical adsorption of the antioxidants from the extract on the surface of the Mild Steel. The experimental data also, revealed that the adsorption of the antioxidants occurred according to the Langmuir adsorption isotherm. Keywords: Corrosion, Antioxidants, Caesalpinia coriaria, Mild Steel.Downloads
