Abstract
A new thermally stable inorganic ion exchanger tin(IV) silicotungstate has been synthesized and characterized based on ion exchange capacity determinations, distribution coefficients for various metal ions, temperature and electrolyte impact on ion exchanger capacity, FTIR spectroscopy, TGA and ICP studies. The quantitative separations of Hg2+-Pb2+, Cd2+-Pb2+, Mg2+-Pb2+, Hg2+-Cu2+, Hg2+-Ni2+ and Hg2+-Zn2+ have been achieved on tin(IV) silicotungstate columns. Separations of binary mixtures using tin(IV) silicotungstate columns found to be 98-100 %.
