Summary

The effect of perchlorate, chloride, sulphate, phosphate and fluoride on the fluorimetric determination of uranium after the extraction of uranium into methyl isobutyl ketone from acid-deficient aluminium nitrate solution has been established. Recoveries of uranium from perchlorate and sulphate media after addition of 1 ml of 15M nitric acid are 100%. Chloride interferes, and a correction must be made to compensate for the anion effect. Phosphate and fluoride in amounts up to 25 mg give recoveries of at least 95%. The anion effect may be minimized by increasing the volume of the organic phase.

Zusammenfassung

Der Einfluß von Perchlorat, Chlorid, Sulfat, Phosphat und Fluorid auf die fluorimetrische Bestimmung von Uran nach dessen Extraktion mit Methylisobutylketon aus Aluminiumnitratlösung mit Säuremangel wurde festgestellt. Aus perchlorat- und sulfathältigen Medien wird Uran nach Zugabe von 1 ml 15-m Salpetersäure zu 100% wiedergefunden. Chlorid stört; zur Kompensation dieses Anioneneffekts muß eine Korrektur angewendet werden. Mengen bis zu 25 mg Phosphat oder Fluorid bewirken, daß höchstens 95% Uran wiedergefunden werden. Der Anioneneffekt kann durch steigende Volumina organischer Phase herabgesetzt werden.
