Anodic dissolution of metals under mass transport control

Résumé

This paper is focussed on anodic dissolution processes controlled by mass transport. After the recall of the results obtained for a classic redox system, four examples are discussed : 1. (i) iron dissolution in sulphuric acid for which a liquid layer of high visosity is formed at the interface; 2. (ii) copper dissolution in hydrochloric acid and 3. (iii) in phosphate acid, where in both solutions a solid salt layer is existing at the electrode surface; and 4. (iv) nickel dissolution in sulphate acid media, where a very high Schmidt number is involved in the mass transport. On the basis of the analysis of steady-state results and electrohydrodynamic impedance, it is evidenced that each system needs a particular description.
