QUANTITATIVE SEPARATION OF METAL IONS FROM CERTAIN MULTI-MINERAL SUPPLEMENTS USING COMPOSITE EXCHANGE MATERIAL: TIN (IV) TUNGSTOSELENATE - 1, 10 PHENANTHROLINEE. LAIQ, S. JABIN AND N. SHAHID
Composite ion exchangers have several specific features which have led to their various applications in diversified fields of sciences. Progress in the technology of retrieval of materials from industrial, pharmaceutical, nuclear wastes has necessitated the synthesis of highly selective ion exchange materials. An essential feature of composite ion-exchanger is the more excellent selectivity they offer than conventional ion exchangers. Such composites have played a significant character in the field of separation sciences. Composite ion exchange materials were prepared by introducing an organic moiety (1, 10 phenanthroline) in the matrix of the inorganic ion exchanger tin (IV) tungsto-selenate. Sorption studies of some analytically essential metal ions have been performed by column chromatography using suitable solvent systems quickly. The quantitative separation of iron and zinc from some multi-mineral supplements has been reported in this paper. This method is easy, rapid and, extremely selective with good precision and accuracy within the experimental error range (Â±2%).
