چکیده | ||
Inhibition action of seroquel on corrosion of zinc in 0.1 M HCl solution was investigated using weight loss, electrochemical potentiodynamic polarization and impedance spectroscopic techniques. Corrosion inhibition efficiency showed the positive effect with increase in concentration of inhibitor and with the increase in temperature. Results obtained from all the methods are in good agreement with each other. Inhibition effect of inhibitor is due to the adsorption of seroquel molecule on zinc surface from bulk of the solution and the process of adsorption follows Temkin’s adsorption isotherm. Potentiodynamic polarization studies revealed that seroquel acts as a mixed type of inhibitor. Corrosion inhibition mechanism is explained by activation and thermodynamic parameters. Surface morphology of the corroded metal was studied by scanning electron microscopic studies and FT-IR spectrum of the corrosion product further confirms the process of adsorption of seroquel on metal surface. | ||
