  • Publication number: 20230357287
    Abstract: The present invention disclose a N,O-type multidentate functional monomer(AAPTS-COOH), a preparation method thereof and an application thereof in ion-imprinted polymers, and belongs to the technical field of separation materials. The N,O-type multidentate functional monomer of the present invention is obtained through the Michael addition reaction of N-aminoethyl-?-aminopropyltrimethoxysilane and acrylic esters, bonding an ester group to the amino group and imine group of N-aminoethyl-?-aminopropyltrimethoxysilane, and hydrolyzing the ester group with a trifluoroacetic acid solution. The 2 nitrogen atoms and 3 oxygen atoms in the functional monomer can coordinate with metal ions. The N,O-type multidentate functional monomer prepared by the present invention can be used to prepare an ion-imprinted polymer (IIP). The imprinted material has high selective adsorption capacity for copper ions and nickel ions. In addition, the IIP synthesis method based on AAPTS-COOH of the present invention has good universality.
