ANTIMONY (V) SILICATE AS A NEW INORGANIC IONEXCHANGERUSEFUL FOR THE REMOVAL OF CHROMIUM (VI),COPPER (II) AND CADMIUM (II)NARESH KUMAR MISHRA, ABHYANSHI TRIPATHI AND NIMISH MISHRAAbstract A new inorganic ion-exchanger antimony (v) silicate (AS) has been synthesized under varyingconditions. Distribution coefficients (Kd) of 20 transition metal ions have been studied in DMW,0.1 mol/dm3 HCl, 0.1 mol/dm3 HCl-10% DMSO (1:10) and 1 mol/dm3 NH4Cl systems. Someanalytically important separations of metal ions have been investigated. The greater selectivitybehaviour of the exchanger for Cr (VI), Cu (II) and Cd (II) has been utilized for the removal andrecovery of these metal ions from dilute water samples.
