【摘要】 建立了电子电气产品塑料部件中限用含溴阻燃剂多溴二苯醚(PBDE)和多溴联苯(PBB)的气相色谱/质谱(GC/MS)联用检测方法,成功应用于10种PBDE和8种PBB化合物的检测。样品经索氏提取器提取、固相硅胶净化小柱净化后,用GC/MS联用仪进行定性和定量特征离子分析。PBDE和PBB的线性分析范围为3.3~3 300 ng(绝对进样量),3种代表性化合物四溴联苯、十溴联苯和十溴二苯醚的加标回收率为76.4%~99.2%,十溴二苯醚的方法精密度为1.3%。结果表明,本方法应用于电子电气产品塑料部件中限用含溴阻燃剂的检测,操作简单,分析结果稳定,重现性好。更多还原

【Abstract】 A gas chromatography/mass spectrometry(GC/MS) method was developed for the determination of polybromodiphenyl ether(PBDE) congeners and polybromobiphenyl(PBB) congeners in plastic parts of electrotechnical products,and it was successfully used in determining 10 PBDE congeners and 8 PBB congeners.Sample was extracted in Soxhlet equipment,and clean-up was performed on a solid-phase column containing silica gel.Identification and quantification analyses were performed in SIM mode of GC/MS.The linear range of PBDE and PBB was between 3.3-3 300 ng,average recoveries from fortified samples expressed with three representative chemicals Tetrabromobiphenyl,Decabromobiphenyl and Decabromodiphenyl ether were between 76.4%-99.2%,and the relative standard deviation of results from sample containing Decabromodiphenyl ether compound was 1.3%.The results showed that the brominated flame retardants could be analyzed simply by this method and the results were stable and reproducible.更多还原
