摘    要: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1~50μg/L范围内线性良好,19种PBBs单体检出限为0.147~0.230μg/L,相对标准偏差为6.61%~10.5%,加标回收率为61.5%~82.6%。

关 键 词:多溴联苯  DPX萃取  程序升温大体积进样  GC/MS

Abstract:DPX rapid adsorption extraction tip was combined with programmable temperature vaporizer ( PTV) and large volume in-jection coupled with GC/MS to determine 19 polybrominated biphenyls ( PBBs) in water simultaneously.The experiment was con-ducted with the SIM mode.The experimental results showed good linearity ranging from 1 to 50μg/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%.
Keywords:PBBs  DPX extraction  Temperature programming and large volume  GC/MS
