The inhibition efficiency of 5,5 diphenyl 2-thiohydantoin (DPTH) against mild steel (MS) corrosion has been
investigated in 0.1 M HCl solution by using electrochemical techniques and quantum chemical calculations.
The electrochemical measurements indicate that the inhibition efficiencies increase with the increasing concentration
of DPTH. According to polarization measurements DPTH retards both anodic and cathodic reactions.
Thermodynamic parameters and activation energy (Ea) for theMS corrosion have been determined fromelectrochemical
results and discussed. Furthermore, quantum chemical parameters of DPTH have been calculated to
explain the corrosion inhibition mechanism.
