1367318 Electrolytic purification of liquids BATTELLE MEMORIAL INSTITUTE 15 Sept 1971 [15 Sept 1970] 43076/71 Heading B1X [Also in Division C7] An electrolytic method of removing a dissolved or suspended constituent from an ionically conducting solution comprises selective absorbtion on conductive particles. It utilises a cell having two electrodes separated by a porous partition. At least one of the electrode compartments is provided with absorbent partides and means to agitate the solution so that the particles contact the electrode, become electrically charged and so permit selective absorption of the constituents. Container 1 is separated into two compartments 1A, 1B by porous PVC partition 2. Platinised titanium electrode 3A, graphite counter electrode 3B and saturated calomel reference electrode ER and connected to potentiostate PS. The absorbent particles may be iron or activated carbon. The solution is agitated by stirrer 5, by convection currents produced by a heater, or simply by rocking the container. In other embodiments the solution is recycled, if so the inlet and outlet ducts of the compartments may be provided with porous membranes to prevent the escape of the particles. The apparatus may be used for blood dialysis, desalination of sea water or for the absorption of gases dissolved in liquids.
