Preparation and Sorption Properties of Spherical Polyacrylamide-Zirconium Phosphate Ion-Exchanger

Spherical particles of polyacrylamide-zirconium phosphate (PZP) ion-exchanger have been prepared by the conversion of hydrous zirconia with the sol-gel technique using acrylamide and N,N'-methylenebisacrylamide copolymer as binders. Some chemical properties, stabilities, and sorptions of 1-2 valent cations have been studied. An elution curve of 137 Cs is reported, and the effective separation of Cs + , Co 2+ , and Ce 3+ has been achieved with a small column of PZP.
