Abstract: Dialysis is enhanced by using nanoclay sorbents to better absorb body wastes in a flow-through system. Nanoclay sorbents, using montmorillonite, bentonite, and other clays, absorb significantly more ammonium, phosphate, and creatinine, and the like, than conventional sorbents. The clays may be used in wearable systems, such as a wearable peritoneal dialysis system, in which the dialysis fluid is circulated through a filter with nanoclay sorbents. Waste products are absorbed by the nanoclays and the dialysis fluid is recycled to the patient's peritoneum. Using the ion-exchange capability of the nanoclays, waste ions in the dialysis fluid are replaced with desirable ions, such as calcium, magnesium, and bicarbonate. The nanoclay sorbents are also useful for refreshing dialysis fluid used in hemodialysis and thus reducing the quantity of dialysis fluid needed for hemodialysis.
