| Abstract: | A gas chromatography-mass spectrometry（GC-MS） method was established for the determination of polybrominated diphenyl ethers（ PBDEs） in fire-retardant wood. The fire-retardant woods were smashed and extracted by ultrasonic extraction using methylbenzene. The samples were purified through silica column. The extract cleaned- up was identified and quantified for the PBDEs in GC-MS equipped with EI source. The results proved that the limit of detection in fire-retardant wood was 3 mg/kg. The recovery rate was 91.7%, and the range of relative standard deviations was 7.79%. The method which was in high sensitivity, accuracy and precision can be used to analyze the PBDEs in fire-retardant wood. |
