摘要
建立一套准确、高效、快捷的水中多溴联苯醚（polybrominated diphenyl ethers,PBDEs）残留量的检测方法。样品采用二氯甲烷提取,氮吹浓缩,正己烷定容,然后以气相色谱-质谱测定。19种PBDEs组分线性良好,相关系数R2均大于0.99,相对标准偏差（relative standard deviation,RSD）（n=6）为1.5%~5.6%,检出限为0.1~1.0μg/L。PBDE-3和PBDE-209平均加标回收率为84.3%~93.2%,RSD为3.6%~10.1%。结果表明,该方法各项指标均能满足检测工作要求,适用于水中PBDEs残留量的日常检测。
An accurate, efficient and fast method for the determination of residues of polybrominated diphenyl ethersin water using gas chromatography-mass spectrometry （GC-MS） was developed. The sample was extracted usingdichloromethane, concentrated under nitrogen blow, dissolved in hexane, and then detected by GC-MS. The calibrationcurves of all 19 polybrominated diphenyl ethers presented good linearity with correlation coefficients （R2） higher than 0.99.The relative standard deviations （RSD, n = 6） for precision were between 1.5% and 5.6%, and the limits of detection （LOD）were in the range from 0.1 to 1.0 μg/L. The recoveries of PBDE-3 and PBDE-209 were from 84.3% to 93.2%, with RSD（n = 6） between 3.6% and 10.1%. These results displayed that all the evaluated figures of merit of the method could meet theanalytical requirements. Thus, the developed method could be applied in the routine analysis of polybrominated diphenylethers residues in water.
