建立了测定6种苯胺类化合物在车用汽油中含量的气相色谱－质谱法。在优化的色谱条件下，以选择离子监测模式（ SIM）对6种苯胺类化合物进行定性，以苯乙醚为内标进行定量检测。结果显示，6种苯胺类化合物在0.01～10 mg／L范围内呈线性，检出限为0.23～0.34 mg／L；样品加标回收率为92.2％～113.1％；精密度（RSD， N＝6）为0.5％～3.4％。

A gas chromatography-mass spectrometry ( GC-MS) method was developed for the determination of six aniline additives in gasoline for motor vehicles.The gasoline samples were analyzed by GC-MS in selective ion monitoring ( SIM) mode and quantified with as interior label under the optical conditions.Calibration curves of aniline additives were linear in the range of 0.01~10 mg/L with detection limits of 0.23~0.34 mg/L.The recoveries were 92.2%~113.1%and the relative standard deviations ( RSD, N=6) ranged from 0.5%~3.4%.
