ABSTRACT

The known use of alumina as a separation step of 99Mo in acid medium requires, for its proper accomplishment, the determination of both the type of alumina and the separation conditions. Utilization of LEU can involve changes in the nature of the targets and also in the dissolution method, which necessitates the eventual consideration of an acid medium for the attack. A study on molybdenum retention and elution in alumina was performed at laboratory scale, using 99Mo radiotracer. Different kinds of alumina were tested for varying conditions (acidity, temperature and uranium concentration) of the loading solutions. The behaviour of uranium in this proposed separative stage was also studied.
