【摘要】 本文研究了用阳树脂柱和阴树脂柱的两步离子交换法,从1AW废液中分离、提取Tc。 1AW模拟料液在0.1mol.dm^-3HNO₃介质条件下,通过阳树脂柱;再将Tc淋出液部分通过阴树脂柱,用4mol,dm^-3HNO₃淋洗,达到了Tc与其它元素的分离,获得了纯Tc。更多还原

【Abstract】 In this paper the separation and recovery of Tc from a simulated spent nucdear fuel reprocessing waste solution by ion exchange resin method has been studied. Asimulated lAW feed solution is adjusted to pH1 （0.1 mol·dm³）. The solution after passing through the H-type Dowex 50×8 column and the OH-type Dowex 2×8 column, is eluted with 0.1 and 4 mol·dm^-3 HNO₃ respectively. Pure Tc is recovered in the eluate.更多还原
