The invention relates to an electrode assembly for the electrochemical treatment of liquids with a low conductivity. Said assembly comprises electrodes (), between which a polymer solid electrolyte () is situated. The electrodes are pressed against one another by means of a compression device () and are configured in such a way that the assembly can be traversed by the liquid. To produce said assembly simply and to ensure that it is flexible and easy to use, the compression device () is supported on the electrodes ().

Electrode assembly for the electrochemical treatment of liquids with a low conductivity

A method and a device for the regeneration of an electroless metal deposition bath containing hypophosphite ions by electrodialysis is described. The method according to the invention and the device differ from the prior art in that the bath solution is led simultaneously through diluate compartments in a second electrodialysis unit having cathodes and anodes, which compartments are separated from concentrate compartments in the second electrodialysis unit on the cathode side by monoselective anion-exchange membranes and on the anode side by anion-exchange membranes, the diluate compartments and the concentrate compartments in the second electrodialysis unit being disposed alternately to one another.
