| Summary: | Ion-imprinting technology endows with the selective separation for target ions, which has the advantages of high predeterminability, recognition, stability and practicality. The ion-imprinted materials obtained by the ion imprinting technology have the characteristics of simple process, easy operation, good stability and high selectivity. In order to meet the needs of lithium resources, ion-imprinted materials have been used for the development and utilization of lithium resources in water samples with complex compositions. In this article, the characteristics of ion-imprinted materials and their preparation principles were briefly introduced, and the main components of Li<sup>+</sup>-imprinted material preparation systems were summarized. Furthermore, the research progress of Li<sup>+</sup>-imprinted materials was reviewed with emphasis on the current research status of advanced Li<sup>+</sup>-imprinted materials. At present, advanced Li<sup>+</sup>-imprinted materials are mainly prepared by surface ion imprinting polymerization combining with new technologies, such as adsorption columns, magnetic separation, and membrane separation, to enhance selective recognition for lithium and simplify separation and recovery operations. Finally, the problems in the preparation and application of Li<sup>+</sup>-imprinted materials are proposed, and their future development and application prospects were prospected. |
