Özet
The inhibition effect of 2,2?- (((thiobis (4,1 phenylene)) bis(azanylylidene)) bis(methanylyidene)) bis(4-methoxyphenol) (BIS-IMIN) on the corrosion behavior of 304-stainless steel (SS) in 0.5 M HCl solution was studied by electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization techniques. SEM, FT-IR, 1H-NMR, 13C-NMR methods used for characterization of BIS-IMIN. Potentiodynamic polarization curves indicated that BIS-IMIN act as mixed type inhibitor. The adsorption of the inhibitor was more suited with the Langmuir adsorption isotherm and kinetic parameters Kads, ?Gads, Ea, ?Hads, ?Sads were determined at room temperature. The results showed that BIS-IMIN performed well inhibiting effect for the corrosion of the SS. © 2016, Sociedad Chilena de Quimica. All rights reserved.
