Abstract
The invention relates to an electrochemical process for the production of metal hydroxides and/or metal oxide hydroxides comprising metal ions and hydroxide ions, and a device for the performance of the process. The metal hydroxide and/or metal oxide hydroxide is formed in the chamber K bordered on a cathode side by a bipolar diaphragm and the required hydroxide ions originated by means of the bipolar diaphragm, whereby the anion-selective layer is arranged on the anode side. The metal ions are either fed to the chamber K in the presence of an agent complexing the metal ions and located in the chamber K at a pH of greater than 7 or are formed in the chamber K. T...
