摘　　要：采用带有大气压化学电离离子源的超高效液相色谱-串联质谱仪,研究了水中2种典型硝基多环芳烃——1-硝基芘和1,8-二硝基芘的定量分析条件.结果表明,在多反应监测模式下,可直接分析水中痕量1-硝基芘和1,8-二硝基芘.其线性范围分别为0.72~12μg/L和0.48~48μg/L,相关系数分别为0.999 0和0.999 2,回收率分别为97.67%~104.44%和93.33%~103.13%,方法检出限分别为0.21μg/L和0.15μg/L,定量限分别为0.72μg/L和0.26μg/L.Using ultra performance liquid chromatography-tandem mass spectrometry equipped with atmospheric pressure chemical ionization ion source, this work established the quantitative analysis methods of two typical nitro polycyclic aromatic hydrocarbons, that is, 1-nitropyrene and 1, 8- dinitropyrene. The results showed that both 1-nitropyrene and 1,8-dinitropyrene could be determined directly under multiple reaction monitoring mode. Both 1-nitropyrene and 1,8-dinitropyrene displayed excellent linearity in the concentration range of 0. 72-12 μg/L and 0.48-48 μg/L, the correlation coefficients of the calibration curve were 0. 999 0 and 0. 999 2. The average rates were in the rang of 97.67%-104.44% and 93.33%-103.13%. In addition,the limits of detection of 1-nitropyrene and 1,8-dinitropyrene were 0.21 μg/L and 0.15 μg/L,and the limit of quantitation were 0.72 and 0.26μg/L respectively.
