Patent Title: Anion-cation double exchange type copper (II) ion surface imprinted polymer and preparation method thereof
Publication date: 2018
Publication number: CN107641174A

Abstract: The invention provides polystyrene-supported anion-cation double exchange type copper (II) ion surface imprinted polymer which is prepared by performing copolymerization with skeleton monomers on polyenoic allyl ammoniated polystyrene surfaces by taking an unsaturated quaternary ammonium cation-modified sulfated aldoxime copper (II) complex as a functional monomer and polyenoic allyl ammonium saltas a cross-linking agent; the polymer can be used as solid-phase blotting bi-site extractant for copper (II) to perform selective enrichment and separation of copper (II) ions in various aqueous systems; the polymer has the function and characteristic of simultaneously extracting counter-anions and can be used in methods for removing the copper (II) ions in the various aqueous systems and methodsfor detecting, and separating and enriching the copper (II) ions in the various aqueous systems in an auxiliary manner; and the anion-cation double exchange type copper (II) ion imprinted polymer canbe in forms of foam, diaphragm plates, fibrils or particles.
