AB  - The direct trace analysis of phenolic compounds in aqueous samples was performed 
      by headspace solid-phase microextraction/gas chromatography (HS-SPME/GC). A 
      laboratory made poly (phthalazine ether sulfone ketone) (PPESK, 30 microm) coated 
      fiber was used to extract the phenols from aqueous samples. The parameters 
      affecting the extraction efficiency, such as extraction temperature and time, pH 
      value, and salt concentration, were optimized. The low pH value and high salt 
      concentration can increase the extraction efficiency of phenols. The limits of 
      detection (LODs) were from 0.003 to 0.041 microg/L, which were within the range 
      of EPA Method 604. The relative standard deviations (RSDs) were less than 16%. 
      Compared with commercial polyacrylate (PA) fiber (85 microm), the PPESK fiber 
      shows high affinity toward phenolic compounds, and therefore, high absolute 
      recoveries. The phenols were detected with the recoveries of 100.5%-111.8% for a 
      tap water sample and 94.8%-117.3% for a seawater sample at the spiked level of 20 
      microg/L.
