Muddukrishna, D. Narasimnan, C. Desai] A new technique for the separation of99mTc from low specific activity99Mo is reported. A separation based on the principle of precipitation of99Mo as calcium molybdate has been investigated. On precipitating99MoO 4 2− from alkaline solution as calcium molybdate under controlled conditions, the99mTcO 4 − is found to remain quantitatively in the supernatant solution with little carry-over of99Mo. This calcium molybdate (99Mo) could be redissolved and reprecipitated at regular intervals, yielding99mTc quantitatively in aqueous neutral solutions. Calcium molybdate precipitates containing up to 1.5 GBq of99Mo and 130-180 mg of molybdenum were prepared and evaluated. The performance in terms of repeated99mTc separation gave yields of 75-93% with acceptable readionuclidic and radiochemical purity. Akadémiai Kiadó, 1990 Muddukrishna S.
