Method for preparing magnetic bisphenol A molecularly imprinted polymer

The invention discloses a method for preparing a magnetic bisphenol A molecularly imprinted polymer. The method comprises the steps: 1) dissolving a bisphenol A template molecule with a functional monomer and alkylated cyclodextrin in 10 ml of DMSO, fully mixing, and storing for 12 hours in dark; and in the mixture, respectively adding ferroferric oxide microspheres, a crosslinking agent, an initiator and a dispersion medium water, and stirring evenly; 2) transferring the obtained mixed solution to a flask, continuously introducing nitrogen in the reaction process, and carrying out a reaction for 24 h at the temperature of 70 DEG C; and after the completion of the reaction, carrying out magnetic separation of the product; and 3) carrying out Soxhlet extraction with a 20% acetic acid methanol solution, to obtain a grey powder having BPA removed, carrying out vacuum drying of the obtained product, and thus obtaining the magnetic bisphenol A imprinted polymer Fe3O4@TiO2-MIPs. The magnetic bisphenol A molecularly
