In this study the inhibitive effect of Methyl Para Tollyl Sulphide (MTS) on metal corrosion in 3M HNO3was investigated using weight loss, electrochemical impedance spectroscopy(EIS), and potentiodynamic polarization(PDP). MTS act as an inhibitor for the acid corrosion of metal, Inhibition efficiency of the metal increased with an increase in concentration of MTS but decreased with increase in temperature. The maximum inhibition efficiencies obtained were 93.1%,for weight loss, EIS and PDP technique, respectively. The adsorption of MTS on the metal surface was found to be spontaneous and obeyed Temkin’s adsorption isotherm at all studied temperatures. The adsorption is a mixed adsorption involving both chemisorption and physisorption. The metal surface was assessed using scanning electron microscopy (SEM) . Atomic force microscopy(AFM) which also revealed the protective ability of the MTS for metal in HNO3 solution.
