A new thermally stable three component inorganic ion exchanger stannic phosphosilicate have been synthesized and the sample with maximum ion exchange capacity and almost total regeneration has been chosen for further studies. The product has been characterized by IR and TGA Studies. The chemical composition (sn : P: Si = 2:4:1), chemical stability, distribution coefficient for 10 metal ions, change in exchange capacity with ionic radii, effect of temperature on ion exchange capacity and effect of electrolyte concentration on distribution coefficients for certain metal ions have been studied. The quantitative separations like Pb (II) from Hg (II), Mg(II), Ni (II) and Zn(II) and Hg (II) from Cu (II), Cd (II) and Ni (II) were carried out. The recovery ranged from 94 to 100% with a variation of 2% for repetitive determinations. A few ternary separations such as Hg (II) Zn (II) Pb (II), Hg (II) Ni (II) Pb (II) and Hg (II) Cu (II) Pb (II) were also achieved on tin (IV) phosphosilicate columns.
