Publication date: 2018
Publication number: CN107649101A

Abstract: The invention discloses a sulfhydryl-functionalized titanium dioxide molecularly imprinted composite and an aqueous-phase preparation method and application thereof. The molecularly imprinted composite is prepared by mainly using activated titanium dioxide-mercaptan as an imprinting carrier, 2,4-dinitrophenol as a template molecule, and o-phenylenediamine as a functional monomer and a cross-linking monomer for polymerization in an aqueous phase under the initiating effect of ammonium persulfate to form a molecularly imprinted polymer, and eluting the template molecule in the molecularly imprinted polymer. The molecularly imprinted composite can be used to remove the 2,4 dinitrophenol in water. The molecularly imprinted composite has strong affinity to pollutants, good selectivity, high processing efficiency, wide application range and no toxic effect on the environment.
