| Abstract: | The method was established for polycyclic aromatic hydrocarbons determination by continuous aqueous sample flow-solid phase micro extraction/gas chromatography. The flow and solution volume on the effects of extraction were discussed. The good linear in the range from 0 μg/L to 40 μg/L, the detection limits of 8 kinds of polycyclic aromatic hydrocarbons from 0.05 μg/L to 0.5 μg/L, the relative standard deviation of samples 〈7% , the recoveries from 87.0% to 112%. |
