Studies on Efficacy of Ion Exchangers on the Removal of Metal ions and Hazardous Dyes from Aqueous Solution


A heteropoly acid salts of Tin(IV) molybdosilicate inorganic ion exchanger has been synthesized by co-precipitation method and well characterized by different instrumental techniques. The ion exchanger shows high ion exchange capacity and chemical stability in various solvent systems. Cationic and bifunctional nature of the exchanger was obtained from pH titration studies. Distribution coefficient of different studies of different metal ions on the exchanger shows that the material is highly selective for Hg(II) and Pb(II) ions. Analytical applicability of the exchanger has been demonstrated by achieving some binary separation of metal ions, quantitative separation of Hg(II) and Pb(II) from industrial waste water. Also, sorptive removal of hazardous dyes methylene blue and crystal violet from aqueous solution were achieved using the ion exchanger.
