Abstract: Production of an alkali metal originating from alkali metal amalgam comprises using electrolysis using an anode containing an alkali metal amalgam, an alkali metal ion conducting solid electrolyte and a liquid alkali metal as cathode. An Independent claim is also included for an integrated process for the manufacture of chlorine comprising carrying out chloro-alkali electrolysis forming elementary chlorine and alkali metal amalgam, and then carrying out the above alkali metal production process.

Abstract: Proposed is an electrolytic method for the production of sodium and aluminium chloride in an electrolytic cell with an aluminium anode and a sodium cathode separated from each other by a sodium-ion-conducting solid electrolyte. In the anode region, molten electrolyte containing essentially sodium tetrachloroaluminate is electrolysed, the aluminium chloride produced being evaporated out of the cell and the sodium produced being tapped off from the cathode region.

Abstract: A process is described for the separation of metal ions from process water and waste water by the use of an electrically conducting filter aid layer polarised as a cathode, the potential of which is at least 50 mV more negative than the redox potential of the metal ions to be separated, the filter aid layer being permeated by the metal ion-containing water and being cyclically regenerated at intervals of 2 to 180 minutes by means of backwash, separation and flooding processes.
