摘要
本文从理论上探讨了络合交换液膜分离稀土的机理，并将其应用于稀土元素的相互分离。实验结果表明，在适当的条件下，采用络合交换液膜分离性质相似的稀土元素镝和铥，可以显著地改善稀土分离效果，达到有效分离稀土镝和铥的目的，实验结果和理论预测相符合。
A complex exchanging emulsion liquid membrane for mutual separation of rare earth is introduced and its mechanism is also studied. The experimental results show that the selectivity of membrane can be enhanced greatly and the rare earth elements dysprosium and thulium can be separated effectively by the presented complex exchanging emulsion liquid membrane under a appropriate experimental condition. The obtained result is in good agreement with the theoretical predication.
