    Abstract
    Continuing to study the inhibition of corrosion, 5,5-diphenyl-2-thioxoimidazolidin-4-one (PTI) has been tested as a corrosion inhibitor for mild steel (MS) in an aggressive 1 M HCl solution by chemical and electrochemical techniques: weight loss, potentiodynamic polarization (PDP), electrochemical impedance spectroscopy (EIS), scanning electron microscopy (SEM) and energy-dispersive X-ray (EDX) analysis, UV-Visible. Inhibitory efficacy increases with increasing inhibitor concentration and decreases with increasing temperature. The studied inhibitor is more efficient (99.2%) at 298 K at an optimal concentration of 1mM. The PDP study revealed that PTI behaved as mixed type of inhibitor. In addition, the PTI inhibitor obeys the single layer adsorption isotherm of Langmuir. The quantum chemical calculations, molecular dynamic (MD) simulation studies fairly well agreed with the experimental measurements.
