Abstract

The inhibition efficiency of ofloxacin, a fluoroquinolone, on the corrosion of copper in acids has been studied employing polarisation, EIS and weight loss measurements. Ofloxacin had a high inhibition effectiveness, and the inhibitory activity was mixed in nature but mainly cathodic in character. The method of inhibitor adsorption onto the metal surface was identified by determining the potential of zero charges. The activation energy (Ea) and thermodynamic parameters such as the adsorption equilibrium constant (Kads) and the free energy of adsorption (ΔGads) were estimated using the temperature dependence of corrosion rates. The fact that the free energy of adsorption is near to -40 kJmol-1 showed that adsorption occurred via electrostatic coulombic attraction and chemisorption and that the Langmuir adsorption isotherm was followed. Among the potassium halides, only KI improved the inhibition efficiency of ofloxacin by synergism. The structural features obtained by quantum chemical calculations were also supportive of the experimental results.
