前言1958年英国原子能委员会发表的报告中,对四氟化铀中氯化物测定采用蒸馏法把氯分离,然后用氯化银比浊法测定,方法繁琐、费时,分离一个样品需要一天时间。美国原子能委员会爱达荷报告述及在后处理工艺溶液中有大量铀、铁、镍等元素存在,可直接采 Preface In a report published by the British Atomic Energy Commission in 1958, the chlorine was separated from the chloride in uranium tetrafluoride by distillation and then measured by silver chloride nephelometry. The method was tedious and time consuming. It took one day to separate one sample. The American Atomic Energy Commission Idaho reported that there is a large amount of uranium, iron, nickel and other elements in the after-treatment process solution that can be directly collected
