| 建立DPX快速吸附萃取、程序升温（PTV）大体积进样与气相色谱/质谱（GC/MS）联用， SIM模式同时测定水中19种多溴联苯（PBBs
）单体的方法。该方法在PBBs质量浓度1~50 μg/L范围内线性良好，19种PBBs单体检出限为0.147~0.230 μg/L，相对标准偏差为6.61%~10.5%，加标回收率为61.5%~82.6%。 |

| Abstract: |
| DPX rapid adsorption extraction tip was combined with programmable temperature vaporizer （PTV） and large volume injection coupled with GC/MS to determine 19 polybrominated biphenyls （PBBs
） in water simultaneously. The experiment was conducted with the SIM mode. The experimental results showed good linearity ranging from 1 to 50 μg/L， and the detection limits of 19 PBBs monomer were between 0.147 and 0.230 μg/L. The relative standard deviation was between 6.61% and 10.5%. Standard addition recovery was in the range of 61.5% to 82.6%. |
