摘要
对传统的多溴联苯醚（PBDEs）高效液相色谱分析法做了改进．以异丙醇作为溶剂，索氏提取待处理样品；用Acclaim120C18（5μm，250mm×4．6mm）色谱柱。以Na2HPO4、KH2PO4缓冲液和甲醇作为流动相进行梯度洗脱，检测波长为225nm．该法检出限为1～4mg／L，平均回收率为99．29％～100.70％，RSD为0．03％～0．52％．本方法操作精密度和准确度高，可作为PBDEs高效液相色谱分析方法．
Determining Polybrominated Diphenyl Ethers （PBDEs） by high performance liquid chromatography was described. Using Acclaim ~ 120 C18 Column（5μm 250 mm×4.6mm）, Ultraviolet absorption detector（225nm）, gradient eluent as mobile phase, the analytes were quantified using external standard calibration curves. The limit of detection is 1~4 mg/L. The results showed that the relative standard deviation （RSD） from 0. 03% to 0. 52%. The recoveries ranged from 99. 29% to 100.70%. The results indicate this method could meet the demand of analysis PBDEs.
