| 摘 要： | 采用索氏抽提、多层硅胶氧化铝复合柱净化和GC-NCI-MS检测对沉积物中的多溴联苯醚(PB-DEs)进行定量分析，以建立沉积物中多溴联苯醚的分析方法，指示物回收率为69．1％-118．3％，绝大多数目标化合物的回收率为65％-114％，沉积物样品的平均标准偏差为12．7％。

| Abstract: | A method for the determination of polybrominated diphenyl ethers (PBDEs) in sediments was developed. The method based on Soxhlet extraction, multilayer silica and alumina column for clear-up and GC-NCI-MS for final determination. Satisfactory recoveries and replicabilities were obtained. The recoveries of surrogates and the target compounds ranged from 79. 6%-118. 3% and 61. 8%-114. 2% , respectively, and the average relative standard deviations (RSD) for the replicate analyses of PBDEs in two sediment samples were 12. 7% . |
