Ion-imprinted mesoporous materials have high adsorption capacity and adsorption selectivity and stability characteristics, this materials have a broad application prospects. This article summarizes the preparational methods of ion-imprinted mesoporous materials including both the stepwise synthesis and one step synthesis,and focuses on the research and application of their adsorp-tion and separation of heavy metals. Furthermore,this paper briefly introduces the principle of mesoporous materials’adsorption of heavy metal ions,and points out the problems and future development trend in preparation and application of ion-imprinted meso-porous materials.
