AB  - [60]Fullerene functionalized magnetic nanoparticles (Fe(3)O(4)@SiO(2)@C(60)) were 
      prepared and characterized by transmission electron microscope, vibrating sample 
      magnetometer and infrared spectroscopy. The Fe(3)O(4)@SiO(2)@C(60) was then 
      applied for the magnetic solid-phase extraction of 16 priority pollutants 
      polycyclic aromatic hydrocarbons (PAHs) in tea samples. The analyses were 
      performed on gas chromatography-mass spectrometry (GC-MS) using selected ion 
      monitoring (SIM) mode. Parameters affecting the extraction, including sorbent 
      amount, desorption solvent, salt concentration, pH and extraction time were 
      investigated. Under optimized conditions, the developed method based on 
      Fe(3)O(4)@SiO(2)@C(60) gave detection limits of 0.8-14.3 ng L(-1), and 
      quantification limits of 2.6-47.6 ng L(-1) for 16 PAHs, respectively. The spiked 
      recoveries of the target PAHs in tea samples ranged from 92.4% to 106.9%. The 
      intra-day and inter-day relative standard deviations (RSDs) were lower than 8.7% 
      and 10.6%, respectively. These results demonstrated that the established method 
      could be applied to the analysis of PAHs at trace level in tea samples.
