AB  - The present work reports preparation of ordered mesoporous carbon (OMC) film 
      supported on a graphite fiber as a new type of solid-phase microextraction (SPME) 
      fiber for determination of benzene series from aqueous media. The strategy for 
      the supported OMC film preparation was combined dip-coating technology with 
      solvent evaporation-induced self-assembly (EISA) approach. A graphite fiber was 
      immersed in an ethanol solution containing phenolic resin and Pluronic triblock 
      copolymer. Upon solvent evaporation and subsequent pyrolysis under 700  degrees C, the 
      phenolic resin and the surfactant self-assembled on the surface of the graphite 
      fiber to form smooth OMC film. X-ray diffraction (XRD), transmission electron 
      microscopy (TEM) and nitrogen isothermal adsorption results indicate that the 
      resultant OMC film possesses well-ordered two dimensional hexagonal mesostructure 
      with pore diameters of 4.5 nm and BET surfaces of 630 m(2)/g. Scanning electron 
      microscopy (SEM) studies show the supported OMC film with thickness at 8.5 mum is 
      continuous and defect-free. The SPME efficiency of the OMC fiber was evaluated by 
      analysis of five benzene series (benzene, toluene, ethylbenzene, p-xylene and 
      m-xylene) from water samples by gas chromatography-flame ionization detection 
      (GC-FID). The analysis results indicate that the prepared OMC fiber has wide 
      linear ranges (0.5-500 mug/L), low detection limits (0.01-0.05 mug/L) and good 
      repeatabilities (4.0-5.8% for one fiber, 2.9-8.7% for fiber-to-fiber). Compared 
      with commercial counterparts, the OMC fiber exhibits improved extraction 
      efficiency for benzene series and PAHs.
