Synthesis, Characterization and Analytical Applications of Antimony(III) molybdoarsenate as a Cation Exchanger and Selective for Pb(II) and Cu(II) Ions

These three component inorganic ion-exchanger was synthesized under different condition. The most thermal and chemical properties of this material is prepared by intermixing solutions of sodium molybdate (0.1 M), sodium arsenate (0.1 M) and antimony(III) chloride (0.1 M) solution in different volume ratios at pH-1. The Ion-exchange capacity of all the samples was determined by column process. The selected sample was synthesized in bulk for detailed studies. Its ion-exchange capacity of synthesized material for Na+ has been found to be 2.30 meq/g. Characterization of the prepared material was done by different parameters like FTIR, TGA curve, X-ray diffraction, and other studies include pH titration, Kd values, thermal & chemical stabilities. The synthesized ionexchanger has been demonstrated by achieved binary and water softening separations for different analytical practical uses. keywords: Cation-exchanger, pH titration, Distribution studies, Thermal and chemical stabilities, Binary separation, Hardness of water.
