AB  - The application of sulfur microparticles as efficient adsorbents for the 
      solid-phase extraction (SPE) and determination of trace amounts of 10 polycyclic 
      aromatic hydrocarbons (PAHs) was investigated in sea water and wastewater samples 
      using high performance liquid chromatography coupled with an ultraviolet detector 
      (HPLC-UV). Parameters influencing the preconcentration of PAHs such as the amount 
      of sulfur, solution flow rate and volume, elution solvent, type and concentration 
      of organic modifier, and salt effect were examined. The results showed that at a 
      flow rate of 10 mL min(-1) for the sample solutions (100mL), the PAHs could be 
      adsorbed on the sulfur microparticles and then eluted by 2.0 mL of acetonitrile. 
      For HPLC-UV analysis of extracted PAHs, the calibration curves were linear in the 
      range of 0.05-80.0 mug L(-1); the coefficients of determinations (r(2)) were 
      between 0.9934 and 0.9995. The relative standard deviations (RSDs) for eight 
      replicates at two concentration levels (0.5 and 4.0 mug L(-1)) of PAHs were lower 
      than 7.3%, under optimized conditions. The limits of detection (LODs, S/N = 3) of 
      the proposed method for the studied PAHs were 0.007-0.048 mug L(-1). The 
      recoveries of spiked PAHs (0.5 and 4 mug L(-1)) in the wastewater and sea water 
      samples ranged from 78% to 108%. The simplicity of experimental procedure, high 
      extraction efficiency, short sample analysis, and using of low cost sorbent 
      demonstrate the potential of this approach for routine trace PAH analysis in 
      water and wastewater samples.
