建立了采用全自动固相萃取（SPE）净化，浓缩，气相色谱－串联四级杆质谱二级质谱监测（GC －QQQ －MS ／MS）同时测定水中16种多环芳烃的方法。通过优化样品前处理条件和仪器分析条件，取样体积为1.0L 时多环芳烃的最低检出限为0.06～0.27μg／L，最低定量限为0.21～0.91μg／L。针对三组加标浓度为10μg／L、100μg／L、500μg／L 的样品，平行测定6次，平均回收率在79.84％～108.43％，相对标准偏差在3.17％～9.27％。

A method combining auto solid -phase extraction to purify and concentrate samples with gas chromatography-triple quadrupole mass spectrometry (GC -QQQ -MS /MS)to simultaneously determinate 16 polycyclic aromatic hy-drocarbons (PAHs)was proposed.Through optimizingthe sample pretreatment conditions and conditions of instrumental analysis,the limits of detection (LOD)for PAHs ranged from 0.06μg/L to 0.27μg/L.The limits of quantification (LOQ)for PAHs ranged from 0.21μg/L to 0.91μg/L in 1.0L of sample.Three groups of samples spiked with the con-centrations of 10μg/L,100μg/L,and 500μg/L were tested for six parallel determinations.The average recoverieswere between 79.84% and 108.43%.The relative standard deviations were between 3.17% and 9.27%.
