Abstract
The corrosion inhibition efficiency of Schiff base, 3-formylindole-3-aminobenzoic acid (3FI3ABA) on mild steel (MS) in 1.0 M HCl solution have been investigated using weight loss measurements, electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization studies. 3FI3ABA exhibited good inhibition on mild steel in HCl medium even at low concentrations and the inhibition efficiencies increases with increase in concentration of the inhibitor. The adsorption of inhibitor on the surfaces of the corroding metal obeys Langmiur isotherm. Polarization studies revealed that 3FI3ABA act as a mixed type inhibitor. Thermodynamic parameters (Kads, ∆G 0 ads) were calculated using Langmiur adsorption isotherm.
