Investigations on uranyl nitrate solubility in nitric acid in different concentrations at temperatures of 50C

Creators

Description

The solubility of uranyl nitrate was studied in nitric acid solutions of different concentrations at a temperature of 50C. This temperature was chosen with a view to using water as coolant and to facilitate the handling of the strong acid solutions. Accurate curves were established by a multitude of accurate measurements in the high concentration range. Further solubility curves can be derived from this basic curve. Some of the precipitates in the interesting regions of the solubility curve were analyzed. (orig./EF)

Abstract (German)

Gegenstand der vorliegenden Arbeit ist das Loeslichkeitsverhalten des Uranylnitrats in salpetersauren Loesungen unterschiedlicher Konzentration bei der Temperatur von 50C. Diese Temperatur wurde als Ausgangsbasis gewaehlt, um Wasser als Kuehlfluessigkeit verwenden zu koennen und um den Umgang mit den stark konzentrierten Saeureloesungen moeglichst zu erleichtern. Dabei wurde auf genaue und zahlreiche Messungen im konzentrierten Bereich Wert gelegt, um den Kurvenverlauf exakt zu erfassen. Ausgehend von der erhaltenen Basiskurve koennen weitere Loeslichkeitskurven erarbeitet werden. Ausserdem wurden einige der anfallenden Bodenkoerper in den interessanten Bereichen der Loeslichkeitskurve analysiert. (orig./EF)
