6-Bromo-2-methyl-1H-imidazo[4,5-b]pyridine (P1), was investigated for its adsorption and corrosion inhibition traits for mild steel corrosion in 1.0 M HCl solution. Gravimetric, potentiodynamic polarization and electrochemical impedance spectroscopy methods, were used to test the nature of adsorption and the inhibition effect of P1 on the mild steel in acidic media. It was found that the inhibition efficiency improved with the increase of P1 concentration in the acid solution (1.0 M HCl). The adsorption of P1 favored Langmuir adsorption isotherm. The results of corrosion tests confirmed that P1 could serve as an efficient corrosion inhibitor for the mild steel in 1.0 M HCl solution, yielding a high efficiency and low risk of environmental pollution. The theoretical quantum chemical calculations were in good correlation with the experimental results. © 2012-2018 IMIST.
