Corrosion Inhibition and Adsorption Properties of Methocarbamol on Mild Steel in Acidic Medium

Year: 2009

Type: article

Abstract: The corrosion inhibition of mild steel in H 2 SO 4 in the presence of methocarbamol was studied using thermometric and gasometric (hydrogen evolution) methods.The study revealed that the corrosion rate increases with temperature, time and concentration of H 2 SO 4 .Addition of methocarbamol to the corrodent solution lowered the corrosion rate of mild steel.Inhibition efficiency (%I) of methocarbamol was found to increase with concentration and decreased with temperature.Adsorption of methocarbamol molecule on mild steel surface was found to obey the Langmuir adsorption isotherm.The phenomenon of physical adsorption is proposed from the obtained thermodynamic parameters.
