Synthesis and Characterization of Tin (IV) Iodovanadate and its Use as Electron Exchanger

Abstract

Tin (IV) iodovanadate samples were prepared at various mixing ratios and different pH levels by mixing sodium metavanadate and potassium iodate aqueous solution mixture with tin (IV) chloride aqueous solution. The capacity of ion exchange in a material is decreased by increasing the amount of stannic reactants in a mixture, while the capacity of ion exchange is increased by increasing the iodate content. The mixing order, however has no effect on the ability of ion exchange. Characterization of exchanger was done depending on the X-ray diffraction, FTIR, thermal or chemical stability, chemical composition, ion exchange capacity, and pH titration studies. For alkali metal, the capacity of ion exchange increases, other than K+ where the alkaline earth metals have a different trend other than the Ba2+. The research with x-ray diffractions illustrates the semi-crystalline nature of material. It can be revealed from a pH curve of titration, that the material has a weak monofunctional acid behavior. About 200 °C is the stability level of these materials. As per the chemical composition, the mole ratio is 2:3:1 for tin, iodate, and vanadate. This product was used as an electron exchanger. The batch equilibrium technique was used for the ascorbic acid, Sn (II), Fe (II), and N2H4 oxidation.
