Acrylonitrile-based zirconium phosphate (AcZP) has been prepared as a new hybrid cation exchange material. Out of a large number of samples prepared, the one selected for detailed studies has an Na⁺ i.e.c. equal to 2.08 meq/dry g. This new material has been characterized on the basis of its physicochemical analysis like X-ray, IR, SEM, thermal stability, and ion exchange studies. Distribution coefficient (K_d) values for various metal ions in different solvents have been determined to explore its separation potential. The material shows a marked selectivity for strontium. The material may have some applications in the removal of strontium from aqueous nuclear· waste.
