Abstract: Magnetic molecular imprinted polymers (MIPs) with well-defined core-shell nanostructure for extracting tetrabromobisphenol A (TBBPA) have been fabricated by surface molecular imprinting method. Fe3O4@SiO2@MIPs exhibit the good adsorption capacity, high recognition ability and fast kinetics to TBBPA. The maximum adsorption capacity of Fe3O4@SiO2@MIPs towards TBBPA is 88.3 mg g-1, which is 2.3 times as high as that of Fe3O4@SiO2@NIPs. Besides, the material has the short equilibrium time (40 min), the rapid magnetic separation (15.6 emu g-1, 20 s) and the high stability (the adsorption efficiency is at least 85% after seven cycles)
