Synthesis and ion exchange behavior of acrylonitrile-based zirconium phosphate - A new hybrid cation exchanger

Acrylonitrile-based zirconium phosphate (AcZP) has been prepared as a new h ybrid 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/d ry g. This new material has been characterized on the basis of its physicoc hemical analysis life X-ray, IR, SEM, thermal stability, and ion exchange s tudies. Distribution coefficient (K-d) values for various metal ions in dif ferent solvents have been determined to explore its separation potential. T he material shows a marked selectivity for strontium. The material may have some applications in the removal of strontium from aqueous nuclear waste.
