| 摘 要： | 文章建立微波萃取,复合硅胶氧化铝层析柱净化,气相色谱-负化学离子源质谱(GC-NCI-MS)检测对环境底泥样品中七种多溴联苯醚(PBDEs)单体定量分析的方法。底泥样品经25 mL正己烷:丙酮(1:1)萃取剂微波萃取10 min,过复合层析柱净化,70 mL正己烷:二氯甲烷(1:1)洗脱和浓缩后,加入内标物PCB-103后进行内标定量分析,7种PBDEs单体的平均基质加标回收率均值为88.6%~96.7%,相对标准偏差为1.9%~9.3%,方法检出限均小于0.06 ng/g,方法具有良好的重现性,较好的回收率和较高的灵敏度。所建立的分析方法体系已用于长江口近岸沉积物中7种PBDEs残留量的检测,四个实际样品中添加回收率指示物PCB-209,其回收率范围为79.5%~109.6%,相对标准偏差为5.2%~16.5%。

| Abstract: | Method of determination of polybrominated diphenyl ethers(PBDEs)contained in sediments is developed,which involves microwave extraction,multilayer silica and alumina column for clean-up and GC-NCI-MS for final determination. According to the experimental result,average recoveries of spiked samples range from 88.6 to 96.7%,with relative standard deviations between 1.9%and 9.3%,detection limit of the method being less than 0.06 ng/g.Besides,it is reported that a system based on this method has been applied to... |
