| 摘 要： | 将气相色谱-负离子化学源.质谱法(GV-NcI/Ms)和气相色谱-电子捕获检测法(GC-ECD)应用于分析沉积物中6种多溴联苯醚(PBDE8)和5种多溴联苯(PBBs)残留.沉积物样品以V(正己烷):V(丙酮)=1:1作为提取剂,采用索式提取法,提取液经酸性硅胶和中性硅胶层析柱净化和正己烷洗脱后.以PCB-103为内标物和GC-NCI-MS的选择离子监测方式(SIM)进行定性与定量分析,PBDE-209则采用GC-ECD法分析.平均加标回收率为93.3%～110.8%,相对标准偏差为1.2%～8.6%,方法检测限均小于0.20 μg/kg(PBDE-209的方法检测限是7.74 μg/kg),相关系数都大于0.9990.所分析沉积物样品中均含有微量的PBDE-99、PBB-49和PBDE-209.
