A Novel Leaf Extract of Sorghum Vulgare as an Eco-friendly Corrosion Inhibitor for Mild Steel Corrosion in 0.5 M H 2 SO 4
Abstract MS effective corrosion inhibition by SVLE has been investigated using electrochemical methods. Tafel polarization measurements suggested that the reaction at the anode occurred with MS dissolution, due to the strong medium aggressiveness, but SVLE addition led to a corrosion IE(%) of 93.6%, at 298 K. SVLE IE(%) still was 86% at an elevated T of 328 K, which was also confirmed by SEM observations that revealed a protective adsorbed film formed by the inhibitor onto the MS surface.
