本文研究了以EDTA为螯合剂、用加压离子交换螯合排代法分离稀土元素时,排代离子浓度对谱带的移速及延伸、阻滞离子区段的变化和稳定区段稀土重叠区长度的影响。并对螯合排代分离过程中的有关机理进行了探讨。
In this paper, when EDTA is used as a chelating agent and the ion exchange chelating displacement method is used to separate the rare earth elements, the displacement and extension of the substituted ions’ concentration on the band, the change of the blocking ion section and the overlap of the rare earth in the stable section The impact of district length. The mechanism of chelating displacement in the process of separation was also discussed.
