Abstract: The invention provides an active/controllable mesoporous material ion-surface imprinted polymer as well as a preparation method and application of the active/controllable mesoporous material ion-surface imprinted polymer, belonging to the technical field of material preparation and separation. The preparation method comprises the following steps of firstly preparing an amino functional mesoporous material, then preparing a mesoporous material grafted with a chain transfer agent, and reacting the mesoporous material grafted with the chain transfer agent with template ions, functional monomers, a cross-linking agent and an initiator, so as to obtain the mesoporous material ion-surface imprinted polymer. According to preparation method, the problems that the thickness of a surface polymer layer is uncontrollable, template molecules cannot be eluted due to great embedding depth, and the adsorption velocity is low are solved; the active/controllable mesoporous material ion-surface imprinted polymer is mainly used for adsorbing corresponding metal ions in a water solution and has excellent adsorption effect and high adsorption capacity at room temperature, and non-specific adsorption is effectively reduced.
