An improved method and electrolytic cell for the oxidation of nitrogen-containing waste materials in a dialysate stream used for hemodialysis, hemofiltration or peritoneal dialysis comprises a cylinder having a porous anode and a porous cathode spaced apart in the direction of flow. By flowing the spent dialysate in the direction from the anode to the cathode, and applying sufficient voltage to oxidize chloride ion present to activated chlorine, the waste materials are oxidized to chlorinated intermediates. In the vicinity of the cathode, the chlorinated intermediates react further to yield to nitrogen and carbon dioxide, with the chlorine being reduced back to chloride ion. In this way, the dialysate is regenerated without the net evolution of undesirable chlorine species.

A method for regenerating hemodialysate by oxidizing urea-containing organic wastes removed from human blood, said method utilizing a cell defining a flow path for said hemodialysate and having a porous, flow-through anode and a cathode spaced apart in a direction of hemodialysate flow through the flow path, said method comprising: flowing the hemodialysate containing the urea through the cell in a direction from the anode to the cathode so that a major portion of the hemodialysate will pass the anode prior to passing the cathode while maintaining a sufficient electrical potential difference between the anode and cathode to oxidize chloride present in the hemodialysate to chlorine, whereby the urea present is degraded to nitrogen and carbon dioxide and the regenerated hemodialysate is substantially free of chlorine as other than chloride as a result of reduction of the remaining chlorine at the anode.
