Synthesis, properties and application research of atrazine Fe₃O₄@SiO₂ magnetic molecularly imprinted polymer.

Introduction: Magnetic Fe3O4 nanoparticles were prepared by coprecipitation and then were coated with SiO2 on the surface.

Materials And Methods: Fe3O4@SiO2 composite microspheres were modified by KH570. Using molecular imprinting technology, atrazine magnetic molecularly imprinted polymer was prepared by using atrazine as template molecule, methacrylic acid as functional monomer and ethylene glycol dimethacrylate as cross-linkers.
