Abstract
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.
