排代离子在分离稀土离子元素中的作用研究

Study on the Effect of Displacement Ion in Seperating Rareearth Ion Elements

本文研究了以 EDTA为螯合剂 ,用高压离子交换螯合剂排代法分离稀土元素时 ,排代离子对谱带的移速及延伸 ,阻滞离子区段的变化的影响。

The article introdeces the effect of displacement ion on Lanal relocity、band spreading and retardalion ion zone Variation when using hight pressure ion exchanging chelant displacement to separate rareearth ion.The chelant is EnTA.It also study the reaction mechanism of the chelant displacement separation.
