STUDY ON THE SEPERATION OF 97Ru FROM α-IRRADIATED MOLYBDENUM AND THE PREPARATION FOR ITS LABELLED COMPOUNDS.

The selection of optimum condition for separating 97Ru fromirradiated molybdenum target is presented. The chemical behavior of 97Ru before and after seperation is observed. The preparation of 97Ru-oxine and 97Ru-microsphere is studied.From the results of distribution experiment, 1N HNO3 is chosen as the acidity of feed solution. Impurity Mo is absorbed by SnO2 and Tc by AG 1×8 anion exchange resin, then pure 97Ru is obtained.
