AB  - The application of magnetized graphene (G) layers synthesized on the carbon 
      nanofibers (CNFs) (m-G/CNF) was investigated as novel adsorbent for the magnetic 
      solid-phase extraction (MSPE) of polycyclic aromatic hydrocarbons (PAHs) in water 
      samples followed by gas chromatography-flame ionization detector (GC-FID). Six 
      important parameters, affecting the extraction efficiency of PAHs, including: 
      amount of adsorbent, adsorption and desorption times, type and volume of the 
      eluent solvent and salt content of the sample were evaluated. The optimum 
      extraction conditions were obtained as: 5min for extraction time, 20mg for 
      sorbent amount, dichloromethane as desorption solvent, 1mL for desorption solvent 
      volume, 5min for desorption time and 15% (w/v) for NaCl concentration. Good 
      performance data were obtained at the optimized conditions. The calibration 
      curves were linear over the concentration ranges from 0.012 to 100ngmL(-1) with 
      correlation coefficients (r) between 0.9950 and 0.9967 for all the analytes. The 
      limits of detection (LODs, S/N=3) of the proposed method for the studied PAHs 
      were 0.004-0.03ngmL(-1). The relative standard deviations (RSDs) for five 
      replicates at two concentration levels (0.1 and 50ngmL(-1)) of PAHs were ranged 
      from 3.4 to 5.7%. Appropriate relative recovery values, in the range of 
      95.5-99.9%, were also obtained for the real water sample analysis.
