Magnetic microspheres have now been widely used in sample pretreatment and the development and application of magnetic separation techniques have been as a hot topic.In this work, core-shell structure Fe3O4@C@polyaniline magnetic microspheres were synthesized using simple hydrothermal reactions.The carbon-coated magnetic microspheres (Fe3O4@C) were first synthesized by a hydrothermal reaction, and then aniline was polymerized on the magnetic core via another hydrothermal reaction.Then, the obtained Fe3O4@C@polyaniline magnetic microspheres were applied as magnetic adsorbents for the extraction of aromatic molecules due to π-π interactions between polyaniline shell and aromatic compounds.In our study, five kinds of phenols including phenol, 2, 4-dichlorophenol (DCP), 2, 4, 5-trichlorophenol (TCP), pentachlorophenol (PCP) and bisphenol A (BPA) were selected as the model analytes to verify the extraction ability of Fe3O4@C@PANI microspheres.After derivatization, the phenols were detected using gas chromatography-mass spectrometry (GC-MS).
