Method for preparing fudosteine molecularly imprinted polymer

The invention provides a method for preparing fudosteine molecularly imprinted polymer and belongs to the technical field of chemical engineering. The method comprises: dissolving fudosteine serving as template molecules, methacrylic acid serving as functional monomer and an ethylene glycol dimethacrylate serving as a cross-linking agent according to a molar ratio of 1:3-4:10, wherein a pore forming agent is mixed liquid of methanol and methylbenzene in a ratio of 1:1-3; adding azodiisobutyronitrile (AIBN) serving as an initiator; performing polymerization at 50 to 60 DEG C for 10 to 20 hours; milling the product, extracting with methanol-acetic acid solution for several times to remove template molecules, and drying at 60 DEG C and under vacuum to obtain fudosteine molecularly imprinted polymer. The fudosteine polymer prepared by the method can be used for detecting fudosteine residue in the environment or medicaments and the enrichment of trace amount of fudosteine, has the advantages of high speed, high flexibility, high accuracy, high yield, high repeatability and high sensitivity, and has a high application value and a bright market prospect.
