摘要：
The effect of pantoprazole sodium (PAN) on the corrosion of copper in aqueous solutions of 0.5 MH2SO4, 1M HCl and 1 MHClO4 was investigated at 30 degrees C using potentiodynamic polarization and electrochemical impedance spectroscopy techniques. The results obtained showed that PAN could serve as an effective inhibitor for the corrosion of copper in the three tested acid solutions. The order of increasing the value of binding constant calculated for PAN in the three tested acid solutions from the application of different models was perchloric acid > hydrochloricacid > sulphuric acid.
