Abstract
Corrosion inhibition of low carbon steel in 1Â M HCl was investigated in absence and presence of Xanthiumstrumarium leaves (XSL) extracts as a friendly corrosion inhibitor. The effect of temperature and inhibitor concentration was studied using weight loss method. The result obtained shown that Xanthiumstrumarium leaves extracts act as an inhibitor for low carbon steel in HCl and reduces the corrosion rate. The inhibition efficiency was found to increases with increase in inhibitor concentration and temperature. Higher inhibition efficiency was 94.82% at higher level of inhibitor concentration and temperature. The adsorption of Xanthiumstrumarium leaves extracts was found to obey Langmuir adsorption isotherm model. The values of the free energy of adsorption was more than â20Â kJ/mol, which is indicative of mixed mode of physical and chemical adsorption.
