Synthesis of a composite ion exchange material Tin (IV) tungstoselenate - 1, 10 phenanthroline has been achieved by mixing differentvolume ratios of the organic counterpart with the inorganic ion exchangertin (IV) tungstoselenate. Final sample, having 0.88mmoles of 1, 10 phenanthroline per gram of inorganic ion exchanger, was chosen for characterization, including ion exchange capacity, thermogravimetric analysis, and Fourier transform infrared spectroscopy. The ion exchange capacity of Li+, Na+, Ca2+, Sr2+ metals was determined by using the synthesized material. The adsorption behavior of Al3+,Co2+,Ni2+,Cu2+,Cd2+,Pb2+ in various solvent systems have been studied. Based on distribution Coefficient (Kd) values, few analytically necessary separations of metal ions from the synthetic mixture have been achieved on the column of the composite ion exchanger.

AbstractAdsorption behaviors of Se(IV) and Te(IV) on the inorganic ion exchanger ceric tungstate (CeW) was studied under static and dynamic conditions and compared with the adsorption on the organic cation and anion exchangers Dowex-50X8 and AG-2X8, respectively. The radioactive isotopes
