A new type siliceous adsorbent for ammonium ion was used for the dialysate regneration system.
This system is based upon the use of activated charcoal, alumina, urease, and the siliceous adsorbent for ammonium ion named ZEC-50. Waste products (Creatinine, Urea, Phosphate) was succesfully removed from 5-liters of dialysate in an anephric dog with this system. However, for a clinical demonstration it is thought to be necessary to improve the adsorbent for ammonium ion, because a large volume of adsorbent of ZEC-50 is needed according to its capacity of ammonium ion.
As a result of adsorption tests, it suggests that MORDENITE will be one of good adsorbents for ammonium ion in a new type dialysate regeneration system.
