Abstract: The invention discloses a method for preparing a magnetic molecularly imprinted polymer for separating atrazine. The method comprises the following steps of: 1) activating Fe3O4atSiO2 particles, and performing surface modification by using a silane coupling agent to obtain composite magnetic nano-particles; and 2) adding the atrazine and methacrylic acid into an organic solvent and preassembling, adding the composite magnetic nano-particles, a crosslinking agent and an initiator, performing polymerization reaction at the temperature of between 60 and 70 DEG for 20 to 24h in an anaerobic environment, and removing the atrazine to obtain the magnetic molecularly imprinted polymer. The method is easy to operate and is suitable for large-scale production; the time consumption is low; raw materials are cheap and readily available; and membrane materials with micron-scale and nano-scale diameters can be obtained. The invention also provides the magnetic molecularly imprinted polymer prepared by the method. Magnetic molecules are firmly combined, and the magnetic molecularly imprinted polymer is high in stability and has stronger adsorption capacity when separating the atrazine.
