CA 2449512

It is described an electrolysis cell wherein the anodic dissolution of metals is carried out, in particular of metals characterised by a relatively high oxidation potential, such as coppere, or metals with high hydrogen overpotential, for example tin, aimed at restoring both the concentration of said metals, and the Ph in galvanic baths used in electroplating processes with insoluble anodes. The cell of the invention comprises an anodic compartment, wherein the metal to be dissolved acts as a consumable anode, and a cathodic compartment, containing a cathode for hydrogen evolution, separated by a cation-exchange membrane. The coupling of the cell of the invention with the electroplating cell allows a strong simplification of the overall process and a sensible reduction in the relevant costs.

L'invention concerne une cellule d'électrolyse où se produit la dissolution anodique de métaux, notamment de métaux caractérisés par un potentiel d'oxydation relativement élevé tels que le cuivre, ou de métaux à forte surtension d'hydrogène, par exemple l'étain. Cette cellule sert à restaurer à la fois la concentration desdits métaux et le pH dans des bains galvaniques utilisés dans des procédés de galvanoplastie avec des anodes insolubles. Ladite cellule comprend un compartiment anodique, dans lequel le métal à dissoudre agit comme une anode consommable, et compartiment cathodique contenant une cathode pour l'évolution d'hydrogène, ces deux compartiments étant séparés par une membrane échangeuse de cations. L'association de la cellule de la présente invention avec la cellule de galvanoplastie simplifie de façon notable l'ensemble du procédé et diminue sensiblement les coûts.
