Synthetic Inorganic Ion-Exchangers. XVI. Thin-Layer Chromatography of Metal Ions on Zirconium Tungstate: Quantitative Separation of Hg(II) from Several Other Metal Ions and from Mixtures

Abstract

Thin-layer chromatography of 23 metal ions in 10 aqueous and mixed solvent systems has been performed on zirconium tungstate ion-exchange material. Several important binary and ternary separations have been achieved. Quantitative separation of Hg(II) from Pb²⁺, Zn²⁺, Cd²⁺, Bi³⁺, Co²⁺, and mixtures has been achieved using 1,4–dioxane as solvent.
