Abstract
Fluconazole, an antifungal drug, and its ionic liquid derivatives were successfully prepared and evaluated for corrosion suppression on carbon steel in hydrochloric acid solution using electrochemistry estimations. The chemical configuration and characterizations of fluconazolium ionic liquids were verified using FT-IR and nuclear magnetic resonance (1H NMR, 13C NMR). The results demonstrate that the above additives perform as inhibitors in acidic corrosive environments and exhibit a strong trend in which inhibition capability increased with increasing inhibitor dose. At 100 ppm, polarization data revealed that fluconazole and fluconazolium ionic liquids had relatively high inhibition capacity (91.26, 98.77, and 98.03%). Fluconazole and its identified ionic liquid derivatives accumulated on the surface of carbon steel using the Langmuir adsorption isotherm concept.
