| description | An amorphous sample of the new hybrid cation-exchanger EDTA–zirconium iodate was synthesized by the combination of the inorganic ion-exchanger zirconium iodate with the organic EDTA molecule, thereby providing a new class of organic–inorganic hybrid ion-exchangers with better mechanical and granular properties, good ion-exchange capacity (e.g. 2 mequiv Na + /g dry exchanger), good reproducibility, a higher stability and demonstrating selectivity towards heavy metal ions. The physicochemical properties of this material were examined by instrumental analyses, viz. FT-IR spectroscopy, X-ray diffraction studies and TGA/DTA investigations. Assessments of the elution and distribution behaviour were made and pH titrations undertaken to obtain an understanding of the ion-exchange behaviour of the material. On the basis of the distribution studies, the material was found to be highly selective towards the Pb 2+ ion, a highly toxic environmental pollutant. Its selectivity was assessed by examining its use for some important binary separations such as Mg 2+ –Pb 2+ , Cd 2+ –Pb 2+ , Hg 2+ –Pb 2+ , Zn 2+ –Pb 2+ , Cu 2+ –Pb 2+ and Al 3+ –Pb 2+ on a packed column of the material. The practical potential of EDTA–zirconium iodate was explored by separating Mg 2+ and Al 3+ ions quantitatively from a commercially available pharmaceutical formulation, viz. Digene.01. |
