Patent Title: Preparation method and application of molecularly imprinted composite sponge membrane for selectively separating emodin
Publication date: 2018
Publication number: CN107652463A

Abstract: The invention discloses a preparation method of an emodin-separating molecularly imprinted composite sponge membrane, and belongs to the technical field of functional material preparation. The preparation method is specifically as follows: with melamine sponge membrane as a basement membrane, emodin as a template molecule, acrylamide as a functional monomer, ethylene glycol dimethacrylate as a cross-linking agent and azobisisobutyronitrile as an initiator, through combination of a graphene oxide surface modifying technology and a molecular imprinting polymerization technology, the emodin-separating molecularly imprinted composite sponge membrane is prepared. Selective adsorption experiments are used for studying the selective adsorption capacity of the prepared emodin-separating molecularly imprinted composite sponge membrane; selective penetration experiments are used for studying the capacity of the prepared emodin-separating molecularly imprinted composite sponge membrane in selectively penetrating a target (emodin) and non-targets (aloe emodin and emodin methyl ether). Results show that the emodin-separating molecularly imprinted composite sponge membrane prepared by the preparation method provided by the invention has a relatively high specific emodin recognizing capacity and a relatively high emodin adsorbing separation capacity.
