AB  - Fluorenyl functionalized superparamagnetic core/shell magnetic nanoparticles 
      (MNPs, Fe3O4@SiO2@Flu) were prepared and characterized by transmission electron 
      microscope, X-ray diffraction and infrared spectroscopy. The MNPs having an 
      average diameter of 200nm were then used as solid-phase extraction sorbent for 
      the determination of 16 priority pollutants polycyclic aromatic hydrocarbons 
      (PAHs) in water samples designated by United States Environmental Protection 
      Agency (U.S. EPA). The main influencing parameters, including sorbent amount, 
      desorption solvent, sample volume and extraction time were optimized. Analyses 
      were performed on gas chromatography-mass spectrometry (GC-MS) using selected ion 
      monitoring (SIM) mode. Method validation proved the feasibility of the developed 
      sorbents for the quantitation of the investigated analytes at trace levels. Limit 
      of detection ranging from 0.5 to 4.0ng/L were obtained. The repeatability was 
      investigated by evaluating the intra- and inter-day precisions with relative 
      standard deviations (RSDs) lower than 13.1%. Finally, the proposed method was 
      successfully applied for the determination of PAHs in water samples with the 
      recoveries in the range of 96.0-106.7%.
