This paper chose triadimenol as a corrosion inhibitor of copper in 0.5mol/L sulfuric acid. The properties of corrosion inhibition were investigated by the polarization measurement and electrochemical impedance spectroscopy (EIS). Polarization curves showed that both cathodic and anodic processes of copper corrosion were suppressed. The inhibiting efficiency increased as the increment of the inhibitor concentration and reached 86.7% at 50 mg/L. The results obtained from EIS measurements are in line with that obtained from potentiodynamic polarization. Finally, a mechanism of inhibition is proposed and discussed.

Abstract It is known that if unused drugs are improperly disposed, they can pollute the environment. Furthermore, researchers are still trying to find an environmentally friendly corrosion inhibitor. These factors lead to the possible application of unused pharmaceutical compounds as corrosion inhibitors. The feasibility of an anti-inflammatory, analgesic and antipyretic drug, ibuprofen, was evaluated as a potential copper corrosion inhibitor in synthetic acid rain solution. This investigation was performed by applying electrochemical and weight loss measurements and quantum chemical calculations. The results obtained by these techniques revealed the ability of ibuprofen to protect copper from corrosion. The inhibition efficiency of ibuprofen rises with increase in its concentration and can reach a value of 97.3%. The results of surface analysis of treated coupons by scanning electron microscopy and theoretical calculations are consistent with the experimental results.
