The cell for enrichment through anodic dissolution of a metal, apparatus for electrodeposition of metal and electroplating process.

摘要

"The electrolysis cell for restoring the concentration of metal ions in electroplating process.The present invention relates to an electrolysis cell in which the anode dissolution of metals is carried out, in particular metal characterized by a relatively high oxidation potential, such as copper or metal with high sobrepotencial hydrogen, for example. Tin, with the intention to restore both.The concentration of these metals and pH in galvanic baths used in electroplating process with insoluble anodes. The cell of the invention comprises an anode compartment in which the metal to be dissolved acts as a consumable anode, and a cathode compartment which contains a cathode for the release of hydrogen, separated by a membrane exchange of cations.The coupling of the cell of the invention with the electroplating cell allows a great simplification of the overall process and strong, and a significant reduction in the relevant costs.
