ABSTRACT

Background: The corrosion inhibitor 2-(4-chlorophenyl)-4,5-diphenyl-1H-imidazole was studied in a 3.5% NaCl solution. The synthesized corrosion inhibitor was studied using gravimetric analysis and thermodynamic and kinetic parameters. The surface morphology of mild steel was studied using scanning electron microscopy and energy-dispersive X-ray analysis.

Results: The inhibitor's anti-corrosion property increases with increasing solution concentration. It was studied over the range of 100-600 ppm in the presence of a 3.5% NaCl solution. It shows a maximum inhibition efficiency of 91.89% at 600 ppm. As the solution temperature increased, its inhibitory efficiency decreased. Thermodynamic parameters indicate the electrochemical stability and mixed potential of the metal in a corrosive environment. The activation energy of the inhibitor on the metal surface was studied using kinetic parameters.
