ABSTRACT:

In order to combine the qualities of inorganic and organic ion exchangers, a stable material with good chromatographic properties, a new inorganic-organic ion exchanger Titanium (IV) phosphosulphosalicylate(TiPSS) was synthesized. Sample-1 was chosen for detailed ion exchange studies due to its highest ion exchange capacity, good appearance and chemical stability. Characterization of the resin was done by determining ion exchange capacity, distribution coefficients for various metal ions, chemical analysis, pH titration, FT-IR spectra and TG thermal analysis. The distribution coefficients (Kd) of 10 metal ions were determined in different electrolyte/electrolyte concentration. The significance of the exchanger is revealed by the important separations. Based on the difference in distribution co-efficient (Kd) some analytically important binary (Mg2+/Pb2+, Zn2+/Pb2+,Co2+/Pb2+, Ni2+/Pb2+, Ca2+/Mg2+& Zn2+/Ca2 +) and ternary (Mg2+/Ca2+/ Pb2+, Zn+2/Ca2+/ Pb2+ and amp; Co+2/Ca2+/ Pb2+) separations of metal ions have been achieved. Practical utility of the material has been demonstrated by a novel TLC separation technique with the exchanger. It was found to possess high thermal stability and selectivity for lead, thus making it an important exchanger for the environmentalists.
