Abstract
A process and a composite for removing toxic cations and anions from blood or dialysate is disclosed. The process involves contacting blood or dialysate with a shaped ion exchange composite to remove ammonium and phosphate ions. The composite is a mixture of an anion exchange composition such as zirconia and a microporous cation exchange composition formed into a shaped article and optionally containing a binder such as hydrous zirconium oxide. The microporous cation exchangers are represented by the following empirical formula.ApMxZr1−xSinGeyOm  (I)orApMxTi1−xSinGeyOm  (II)
