Rosuvastatin drug as a green and effective inhibitor for corrosion of mild steel in HCl and H2SO4 solutions

The effect of rosuvastatin drug on the corrosion behavior of mild steel in 1.0 M HCl and 0.5 M H2SO4 solutions was investigated using potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and Fourier transform infrared (FTIR) techniques. The inhibition efficiency (IE) was found...
