| Summary: | The inhibitive effect of the extract of Ageratum conyzoides on corrosion of SX 316 steel in HCl solution was determined using weight loss measurement and galvanostatic polarisation techniques. It was found that the presence of the plant extract reduces markedly the corrosion of steel in acid solution and inhibition efficiency ranged between 94.39 ? 99.15 %. The inhibition efficiency increases as the plant extract concentration was increased. The inhibitive effect of A. conyzoides extract (ACE) was discussed on the basis of adsorption of the components on the metal surface. Negative value of energy of adsorption indicates the spontaneity of the process. |
