The invention relates to the technical field of adsorption materials, and particularly discloses a molecularly imprinted
hydrogen bond organic framework adsorption material as well as a preparation method and application thereof. According to the material,
tetra (4-
sulfonyl phenyl)
methane and 1, 1 '-diamino-4, 4'-dipyridyl diiodide are used as construction units to form a
hydrogen bond organic framework substrate, and a hemp essence
drug template molecule is introduced to construct a specific imprinting hole in the hemp essence
drug template molecule. The preparation method is characterized in that the
molar ratio X of template molecules to
tetra (4-
sulfonyl phenyl)
methane is controlled to be 0.05-0.5,
crystallization is performed in a water /
methanol mixed
solvent, and then
elution and activation are performed through an acid solution with the pH being 2-4. The material has the advantages of high adsorption capacity, no less than 58 mg / g of template
molecule adsorption capacity,
high selectivity and rapid
adsorption kinetics, achieves balance within 5 minutes, can efficiently enrich trace hemp extract drugs from a
water environment or
biological fluid, and solves the technical problem that the selectivity, the capacity and the
mass transfer rate of the existing adsorption material are difficult to consider at the same time.
