The observed result reveals that the percentage of inhibition efficacy increased with rise of inhibitor concentration, exposure time and temperature. Thermodynamic parameters (viz; E, Qads, ads, H and S) suggests that the surface assimilation of inhibitor is endothermic and chemisorption process. It follows both Langmuir and Temkin adsorption isotherm. The dissolution products also proved by Ultra-violet, Fourier transform infrared spectroscopy, Energy dispersion X-ray spectroscopy and Scanning electron microscope.
