Claim Text:
1. A dialysis system comprising at least one sorbent device and at least one liquid-liquid counter-current extractor in fluid communication with said at least one sorbent device, wherein said sorbent device contains a source containing urease that hydrolyzes urea to ammonia to form an ammonia-containing dialysate solution from spent dialysate, and wherein said liquid-liquid counter-current extractor comprises a) at least one liquid immiscible with said ammonia-containing dialysate solution, wherein the at least one liquid is an organic solvent, and further comprises b) at least one extractor molecule contained in the liquid that removes ammonia from said ammonia-containing dialysate solution, wherein said ammonia-containing dialysate solution and said at least one liquid immiscible solution containing said at least one extractor molecule countercurrently pass through said liquid-liquid counter-current extractor, and wherein said at least one sorbent device is in fluid communication with a hemodialysis machine or peritoneal dialysis machine to receive said spent dialysate therefrom, and said liquid-liquid counter-current extractor is in fluid communication with said hemodialysis machine or peritoneal dialysis machine, wherein said liquid-liquid counter-current extractor produces regenerated dialysate that is returned by the fluid communication to the hemodialysis machine or peritoneal dialysis machine.
