Determination of 7 Polychlorinated Biphenyls in Soil Samples by Accelerated Solvent Extraction-Gas Chromatography/ Gas Chromatography-Mass Spectrometry

  • 摘要: 建立了土壤样品中7种多氯联苯(PCB 28、PCB 52、PCB 101、PCB 118、PCB 138、PCB 153、PCB 180)的分析方法。土壤样品通过加速溶剂萃取、磺化法结合Florisil 固相萃取小柱净化、电子捕获检测器气相色谱分析测定,并结合气相色谱-质谱进一步确证。结果表明,方法回收率为80.06%~100.28%,相对标准偏差(RSD,n=6)为1.01%~6.28%,检出限为0.15~0.50 μg/kg。用优化的方法测定复杂基质的土壤样品中多氯联苯,具有提取效率高、净化效果好、结果准确可靠、对环境污染小等优点。
