Summary

Separation of uranium(VI) from iron(III), molybdenum(VI), vanadium (V), bismuth(III), zirconium(IV) and thorium(IV) is achieved by liquid-liquid extraction with 4-methyl-3-pentene-2-one (mesityl oxide; MeO) from sodium salicylate media (0.1M, pH 6.0). The extracted species is UO2(HO·C6H4COO)2·2MeO. A procedure for separating 50μg of uranium from mg amounts of the other metals is described.

Zusammenfassung

Die Trennung des U(VI) von Fe(III), Mo(VI), V(V), Bi(III), Zr(IV) und Th(IV) läßt sich durch Flüssig-flüssig-Extraktion mit 4-Methyl-3-penten-2-on] (Mesityloxid, MeO) aus 0,1M Natriumsalicylat bei pH 6,0 durchführen. Die extrahierte Verbindung ist UO2(HO·C6H4COO)2·2MeO. Ein Verfahren zur Abtrennung von 50μg Uran von Milligrammengen der anderen Metalle wurde beschrieben.
