Abstract: The invention relates to a preparation method and an application for magnetic molecular imprinting polymers for selectively separating carbamazepine and belongs to the technical fields of environmental material preparation and pollution regulation. Nanometer ferroferric oxide modified on a surface of chitosan serves as a magnetic medium, molecular imprinting material polymerization is carried out on the surface of the nanometer ferroferric oxide by using a sediment polymerization method, and a magnetic molecular imprinting adsorption agent is obtained after template molecular carbamazepine is eluted. Obtained molecular imprinting composite materials are stable in physicochemical property, have high adsorption capacity and specific identification characteristics on the carbamazepine, have superparamagnetism, can be rapidly separated under an outside magnetic field effect, therefore, interference of a complex substrate in an actual sample is avoided, and sample treatment processes are greatly simplified. The preparation method is simple, reliable and low in cost and has a wide application prospect in analysis, detection and pollution treatment of a complex environment sample.
