中文摘要:
      采用快速溶剂萃取-固相萃取-液相色谱串联质谱法(LC-MS/MS)测定土壤中8种多溴联苯醚类(PBDEs)化合物,通过优化试验条件,使方法在100 μg/L~1 000 μg/L范围内线性良好,方法检出限为085 μg/kg~125 μg/kg。不同土壤样品的8种多溴联苯醚回收率为68.6%~127%,4次测定结果的RSD为4.8%~27.6%。将该方法用于测定电子废物拆解点周边的土壤样品,结果BDE-209测定值为未检出~168 μg/kg,BDE-183为未检出~560 μg/kg,其余6种BDEs均为未检出。
英文摘要:
      Eight kinds of polybrominated diphenyl ethers (PBDEs) in soil were determined by liquid chromatography mass spectrometry(LC MS/MS) with accelerated solvent extraction(ASE) and solid phase extraction(SPE). The linear range of the method was 10.0 μg/L~1 000 μg/L under optimized experimental conditions. The method detection limits were 0.85 μg/kg~1.25 μg/kg . The recoveries of eight kinds of PBDEs in different soil samples were 68.6%~127%, the relative standard deviations (RSD) were 4.8%~27.6%(n=4). The method was applied to the soil samples from around the electronic waste disassembling site. The measurement results of BDE 209 were from undetected to 16.8 μg/kg, BDE 183 were from undetected to 5.60 μg/kg, and other BDES were all undetected.
