The inhibitive behavior and mechanism of benzosulfimide on the corrosion of A3 steel in sulphuric acid medium are studied by weight-loss,polarization curves measurements and electrochemical impedance spectroscopy (EIS) methods. The results show that benzosulfimide is an effective and mixing type inhibitor. It suggests that the adsorption of benzosulfimide on A3 mild steel is chemosorption and heat absorption. The adsorption thermodynamical data is calculated.
