Abstract: | Pyridine based zirconium(IV) phosphate (PyZrP)
and tin(IV) phosphate (PySnP) have been synthesized as new and novel intercalated
ion exchangers. These materials have been characterized using X-ray, IR spectra,
TG, DTG and DTA studies in addition to their ion exchange capacity, elution,
pH titration, concentration and distribution behaviour. The distribution studies
towards several metal ions in different media/concentrations have suggested
that PyZrP and PySnP are selective for Hg(II) and Pb(II), respectively. As
a consequence some binary separations of metal ions involving Hg(II) and Pb(II)
ions have been performed on a column of these materials, demonstrating their
analytical and environmental potential. |
