Abstract: The invention belongs to the field of analysis and detection of metal ions in water environment, and discloses a copper ion imprinted polymer, which comprises a polymer carrier and a functional monomer 1,4 - dihydroxy anthraquinone embedded in the polymer carrier, wherein the polymer carrier uses ethylene glycol dimethacrylate as a monomer. The preparation method comprises the following steps of: (1) mixing the 1,4 - dihydroxy anthraquinone with an organic solvent and a soluble copper salt, adding a crosslinking agent and an initiator agent, and reacting for 18 to 20hr at a temperature of 50 to 65 DEG C in the absence of oxygen; and (2) after washing, adding nitric acid to remove the copper ions. By a way that the functional monomer is embedded in a polymer network and a precipitation polymerization method, the imprinted polymer with selective adsorption for the copper ions is synthesized. The ion imprinted polymer has a specific recognition capability for the copper ions, and has better selectivity. Without connecting a double bond capable of being reacted with the crosslinking agent with the 1,4-dihydroxy anthraquinone in advance, the selection type and scope of the functional monomer is expanded, and the reaction steps are simplified.
