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(PBDEs)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%.
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% .
