Inhibition Action of Mild Steel Corrosion in HCl Acid Medium by Extract of Digera Muricata
S. Aejitha | P. K. Kasthuri
Abstract: The acid extract of Digera muricata is controlling the corrosion of mild steel in 1M HCl has been studied by weight loss method and electrochemical impedance spectroscopy in the absence and presence of Digera muricata extract at different time interval and temperature. The inhibition efficiency increases with increase the concentration of Digera muricata extract and immersion period. The inhibition efficiency increased with increasing temperature. The negative value of the free energy of adsorption indicates spontaneous adsorption. The Digera muricata extract obeys Temkin and Frenmdlich adsorption isotherm. All the reported Digera muricata extract was found to inhibit the corrosion of mild steel in HCl acid media.
