Deterioration Inhibition Of Spherical Shape Of Mild Steel In Acidic Medium By Philanthus embilica.

[摘要] The inhibition of corrosion of mild steel in 1M H2SO4 solution at room temperature by methyl red (2,4-Dimethylamino-2'-carboxylazobenzene), an organic compound 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 acidicmedium and their effects were carefully studied on the corrosion rate of mild steel. The results obtainedshowed methyl red to be an efficient inhibitor in the acid environment with general decrease in corrosion rateas the concentration of the organic compound increases. The adsorption of the inhibitor on the mild steelobeys the Langmuir adsorption isotherm.
