Zusammenfassung

Mit Hilfe der Radiotracer-Technik wurde die extraktion-chromatographische Trennung der Elemente Niob und Tantal voneinander sowie dieser zwei von anderen Elementen untersucht. Für diese Zwecke wurden Säulen aus Polyurethan-Schaumstoff, nach Imprägnieren mit Diantipyrylmethan in Dichlorethan, Tributylphosphat oder Methylisobutylketon, verwendet. Die Trennungen wurden aus HF- und HF/H2SO4-Medien vorgenommen. Eine quantitative Trennung der untersuchten Elemente wurde erreicht.

Summary

The separation of niobium and tantalum from each other and of these from other elements by extraction chromatography, has been investigated by the radiotracer technique. Columns made of polyurethane foam pretreated with diantipyrylmethane, tri-n-butyl phosphate, and methyl isobutyl ketone were employed. The separation was carried out in HF and HF/H2SO4 media. A quantitative separation was achieved for all elements investigated.
