Ac Electrogravimetry contribution to the investigation of the anodic behaviour of iron in sulfuric medium
Résumé
Numerous models for dissolution and passivation of pure iron are proposed in the literature. Electrochemical impedance provides kinetic information but not analytical. An additional ac technique, based on the quartz microbalance, is now associated with electrochemical impedance. The background and the first application of this new technique to iron passivation are presented.
