A new hybrid inorganic-organic cation exchanger acrylonitrile tin (iv) tungstophosphate has been synthesized and its analytical application explored. The effect of experimental parameter such as reagent mixing ratio, temperature effect on ion exchange properties of material has been studied. The material behaves as monofunctional acid with ion exchange capacity of 1.91 and 1.94 meq g-1 was found to be for Na+ and K+ respectively. The chemical stability data reveals that the exchanger is quite stable in mineral acid, bases and fairly stable in organic solvent, whereas thermal analysis shows that the material retain 78.65 % I.E.C upto 400
