Anthranilic Acid as Corrosion Inhibitor for Mild Steel in Hydrochloric Acid Media

The inhibition effect of Anthranilic acid on corrosion of mild steel in 1 M HCl solution was investigated by using traditional weight loss method, Polarization measurements and Electrochemical Impedance Spectroscopy (EIS) measurements. Small amount such as500 ppm of the Inhibitor shows good inhibition efficiency. Polarisation measurements infer inhibitor acts as mixed type inhibitor. Weight loss, Polarisation and Electrochemical impedance results are gives same order of inhibition efficiency
