Abetract-The anodic passivation of iron was examined with respect to the degree of proton hydration as well as the acid structure. The investigation was based on the electrochemical tneasurements, XPS study and sulphur dioxide analysis. When acid concentration is low, the passivity of iron is a resu

Numerous models for dissolution and passivation of pure iron are proposed in the literature. Electrochemical impedance provides kinetic information but not analytical. An additional UC technique, based on the quartz microbalance, is now associated with electrochemical impedance. The background and t
