This paper summarized the preparation method of ionic liquid Levextrel resins and its application in the separation of rare earth. Ionic liquid Levextrel resins is a new type of high efficient separation material with multiple functional groups. The preparation methods include physical immobilization method,chemical immobilization method,solution gel method,and membrane loading method. The carrier is generally high surface porous polymer resin,silicon oxide,etc. Ionic liquid extraction resin are found to be provided with designed structure,and could design and synthesis different properties of the ionic liquid Levextrel resins according to different needs of the structure,overcome some drawbacks of ionic liquids such as the loss of the extraction agent,suitable for highly efficient and highly selective separation of rare earth ions. Ionic liquid Levextrel resins is an effective complement of solvent extraction method.
