Go Preparation and application of a surface ion imprinted polymer

The present invention provides a SiO2 / GO surface of the metal ion imprinted polymer preparation method and application, and preparation technology technical field belongs separating material; especially silica / graphene oxide substrate, a metal ion as a template, even crosslinking agent, functional monomer, crosslinker, initiator, reversible addition - fragmentation chain transfer polymerization of aggregation, SiO2 / GO surface of the metal ion imprinted polymer; solution polymer surface layer thickness is not controllable, adsorption sites uneven distribution point, the template molecule can not be too deep because embedded completely eluted, slow adsorption rate and a chain transfer agent the synthesis steps are complicated, time-consuming and so on; mainly for the selective separation of metal ions in aqueous solution corresponding to, and selective separation the effect is significant, reused multiple times.
