大环多元醚在液膜分离金属离子中的应用

Application of Macrocycle Polyether for Liquid Membrane Separating Metal Ions

本文介绍了大环多元醚做流动载体的液膜用于分离一价金属离子钾和钠、二价金属离子铅以及三价金属离子稀土等的有关应用基础研究。并根据大环多元醚化学的发展和我国丰富的稀土资源提出了该项技术的一点看法。

It is described that the liquid membranes with macrocycle polyethers as mobile carriers are used for separating monovalent (potassium and sodium), divalent (lead) and trivalent (rare earths)metal ions. Some viewpoints about the technique are presented according to the development of macrocycle polyether chemistry and rich resources of the rare earths in our country.
