Corrosion Inhibition of 2-Mercaptobenzothiazole for Carbon Steel in Sulfuric Acid Solution

Abstract:

The inhibition effect of 2-Mercaptobenzothiazole (2-MB) against the corrosion of carbon steel in sulfuric acid solution was studied by weight loss measurement and electrochemical measurements(potentiodynamic polarization techniques). The results show that 2-MB acts as a good corrosion inhibitor in sulfuric acid solution. Adsorption of 2-MB is found to obey Langmuir isotherm. Polarization curves indicate 2-MB is a mixed-type inhibitor. The effects of temperature and sulfuric acid concentration were also studied.
