Physico-chemical Characterization and Application of Newly Synthesized Antimony(III) Molybdoarsenate as a Cation Exchanger and Selective for Pb(II) and Cu(II) Ions

Abstract

The present work is concerned with the new synthesized and characterized three component ion-exchanger. Inorganic cation-exchanger have drawn the attention to their selectivity, temperature, thermal and chemical stabilities. 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. All of the samples' Ion-exchange capacities were assessed using a column technique. For in-depth analyses, the chosen sample was synthesised in large quantities. Its ion-exchange capacity of synthesized material for Na+ has been found to be 2.30 meq/g. The loss of weight and change in colour of the ion-exchanger was observed in each case and ion-exchange capacity was determined by column method. Antimony(III) molybdoarsenate is good ion-exchange capacity and is stable up to a fairly high temperature, and fairly stable in different acidic, basic and organic media. The prepared material was characterised using a variety of parameters, including FTIR, TGA curve, X-ray diffraction, pH titration, Kd values, thermal & chemical stabilities, and other studies. The achieved binary and water softening separations for various analytical practical uses have served as a demonstration of the synthesised ion- exchanger.
