| Abstract: | Solvent extraction of the thiocyanate complexes of titanium, niobium and tantalum allows the separation of micro quantities of these elements. Niobium and tantalum are separated by selective extraction of the fluoro-complexes. Mixtures of Ti and Nb, or of Ti and Ta in ratios of 500 : 1 to 1 : 500 can be separated. For mixtures of the three elements, results were acceptable with Nb : Ta ratios of l00 :1 to 1 : 100. Colurimetric determinations of the three elements are described. |
