摘要
The inhibiting action of O-ethyl-S-2-(2-hydroxy-3,5-diiodophenyl)-2-oxoethylxantogenate (EHDO) on the oxidation of FeS in air-saturated solutions at pH 1.3 and 25 °C was studied using potentiodynamic polarization and electrochemical impedance spectroscopy measurements. The uninhibited and inhibited surfaces were characterized by scanning electron microscopy, energy dispersive X-ray analysis and Raman spectroscopy. It was found that EHDO acts as an anodic inhibitor. Also, it was found that the corrosion of Fe(0) is slower than the oxidative dissolution of uninhibited FeS but faster than the oxidative dissolution of inhibited FeS. This behavior makes EHDO a potential inhibitor of the corrosion of Fe(0) when covered by FeS.
