|
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%。
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%.
