摘　　要：报道了土壤样品中痕量六溴环十二烷（HBCDs）的超高效液相气谱／质谱联用分析方法（UPLC／Ms）。结果表明，该方法在9min内即可完成α—HBCD、βHBCD和γ-HBCD3种同分异构体的分离，回收率为79．3％～109．9％，在2．5～150ng／mL范围内具有较好的线性，R^2为0．991～0．998；α—HBCD、β-HBCD、γ-HBCD的检出限分别为20pg、45pg和15pg。An anal （HBCDs） in soil ytical method has been developed for the determination of hexabromocyclododecanes by ultra performance liquid chromatography with mass spectrometry （UPLC/MS）. The three HBCDs（α-HBCD, β-HBCD and γ-HBCD） were separated in 9 min. The recoveries of the three HBCDs were 79.3%-109.9%, and the method showed good linearity in HBCDs concentrations of 2.5 -150 ng/mL with the correlation coefficient of 0. 991-0. 998. The detection limits of α-HBCD, β- HBCD and γ-HBCD were 20 pg, 45 pg and 15 pg, respectively.
