This paper introduces the basic application of macrocyclic polyether as a mobile carrier liquid membrane for separation of monovalent metal ions such as potassium and sodium, divalent metal ions and rare earths such as trivalent metal ions. According to the development of polycyclic ether chemistry and the rich rare earth resources in our country, some suggestions on this technology are put forward.
