Specific Separation of Gallium,Gold, and Magnesium,and Separation of Be-AI-Ga on Stannic Molybdate Papers

Abstract

Chromatography of 47 cations in 11 solvent systems has been performed on stannic molybdate ion exchange papers. Some difficult separations, e.g., Rb from Cs, Al-Be-Ga, and Tl-In, and specific separations of Ga, Au and Mg from numerous metal ions, have been achieved. R _F values of some common metal ions on these papers have been compared with R _F values of these cations on stannic tungstate and stannic phosphate papers. The preparation of papers is easy and the results are reproducible.
