Abstract
The corrosive behaviour of mild steel in 1M NaOH solutions contaminated with methyl red (2, 4-Dimethylamino-2'-carboxylazobenzene), an organic compound at room temperature was studied using the weight loss technique. The concentration of the methyl red was varied as 1.0%, 2.0%, 3.0%, 4.0%, 5.0% and 6% weight of each alkaline medium and their effects were carefully studied on the corrosion rate of mild steel. The results obtained showed methyl red to be an efficient inhibitor in the alkaline environment with general decrease in corrosion rate as the concentration of the organic compound increases. The Langmuir adsorption isotherm was found to be the best description of the adsorption behaviour of Methyl red on the mild steel surface.
