裂变~(99)Tc~m发生器洗脱液中纯β杂质的分离和测定

摘要: 通过离子交换、活性炭吸附、硫酸盐沉淀等步骤，建立了从裂变￣（９９）Ｔｃ￣ｍ发生器洗脱液中分离和测定纯β杂质的方法。化学产额为７０％左右。方法已用于裂变￣（９９）Ｔｃ￣ｍ发生器洗脱液中纯β杂质的常规检定。

Abstract: SEPARATION AND DETERMINATION OF PURE BETA IMPURITIES IN THE ELUATES OF FISSION ~(99)Tc~m GENERATOR Wang Yongzhen；Min Chenyi（China Institute of Atomic Energy,Beijing 102413）AESTRACT The pure beta emitting impurities in ~(99)Tc~m eluates of fission ~(99)Tc~m generator are separated by the ion exchange，activated charcoal adsorption and sulfate precipitate method and measured by low－levelbeta counter．The chemical yield is about 70％，This method has been used for routine appraisal of be-ta nuclide purity of the fission~(99)Tc~m generator eluates.Key words fission~(99)Tc~m generator eluate pure beta impurities
