摘要: 为建立快速、简便地分析土壤中12种多溴联苯醚(polybrominated diphenyl ethers, PBDEs)质量分数的检测方法,对仪器的参数和样品净化过程进行了优化。通过对比不同仪器参数组合、固相萃取柱种类、活化和洗脱溶剂组合及溶剂洗脱量对样品中12种PBDEs回收率的影响,确定了最优条件。在最优条件下,对实际土样进行加标验证,12种PBDEs的平均加标回收率为90.36%~121.40%,回收率相对标准偏差为4.11%~8.76%,东营油田土壤中PBDEs的质量分数为6.68×10-9~105.68×10-9。本方法使用C18固相萃取柱替代传统复合硅胶柱,简化了样品处理过程,具备操作便捷、稳定性好的优点,适用于大规模土壤样品中PBDEs的检测。
