Abstract: A novel, well-designed magnetic graphene oxide sheet embedded with core-shell molecularly imprinted polymer microspheres (MGO@MIP) was controllably synthesized via a reflux-precipitation polymerization and surface imprinting technique. The as-prepared MGO@MIP was fully characterized and the results reveal that the specific selectivity and remarkable adsorption capacity to pentachlorophenol (PCP) are closely related to the synergetic effect of hydrogen bonding and π-π interactions, which are strongly associated with the solution pH and the distribution of magnetic microspheres on the surface of GO sheets. Under the optimal conditions, i.e., pH of 4.0 and a ratio of monomers to Fe3O4 of 15, the maximum adsorption capacity and the imprinting factor (α) of MGO@MIP towards PCP were 789.4 mg g-1 and 4.36, respectively. The newly synthesized MGO@MIPs has proved to be a great adsorbent for PCP in environmental water
