摘要:The effect of an antibacterial Septazole on the corrosion of copper was studied in 0.1 M HCl at differentconcentrations using potentiodynamic polarization, electrochemical frequency modulation (EFM) and electrochemicalimpedance spectroscopy (EIS) measurements. Potentiodynamic polarization indicated that Septazole acted as mixed- typeinhibitor. EIS measurements were also used to investigate the mechanism of corrosion inhibition. Results obtained fromEFM technique were in agreement with potentiodynamic and EIS techniques. The adsorption of Septazole on the surface ofcopper followed the Langmuir adsorption isotherm at all concentrations and temperatures studied. The reactivity ofSeptazole was analyzed through quantum chemical calculations based on PM3 semi-empirical method to explain theefficiency of this inhibitor as corrosion inhibitors.
