AB  - A magnetic sorbent was fabricated by coating the magnetized graphene oxide with 
      polystyrene (PS) to obtain a sorbent of the type GO-Fe(3)O(4)@PS. The chemical 
      composition and morphology of the sorbent were characterized. The sorbent was 
      employed for the enrichment of polycyclic aromatic hydrocarbons (PAHs) from water 
      samples. Various parameters affecting the enrichment were investigated. The PAHs 
      were then quantified by gas chromatography with flame ionization detection. 
      Linear responses were found in the range of 0.03-100 ng mL(-1) for naphthalene 
      and 2-methylnaphthalene, and of 0.01-100 ng mL(-1) for fluorene and anthracene. 
      The detection limits (at an S/N ratio of 3) range between 3 and 10 pg mL(-1). The 
      relative standard deviations (RSDs) for five replicates at three concentration 
      levels (0.05, 5 and 50 ng mL(-1)) of analytes ranged from 4.9 to 7.4%. The method 
      was applied to the analysis of spiked real water samples. Relative recoveries are 
      between 95.8 and 99.5%, and RSD% are <8.4%. Graphical abstract A magnetic sorbent 
      was fabricated by polystyrene coated on the magnetic graphene oxide for the 
      extraction and preconcentration of PAHs in water samples prior to their 
      determination by gas chromatography with flame ionization detection.
