摘要
建立了高效液相色谱法分析１４种多环芳烃（ＰＡＨｓ）的最佳分离条件及测定的最佳荧光激发、发射波长，多环芳烃化合物的最小检测量从０９０到５５１９ｐｇ，各化合物保留时间的相对标准偏差ＲＳＤ＜０３４％，在所测定的含量范围内具有很好的线性关系。该法用于大气气溶胶中的多环芳烃分析时，气溶胶的萃取物不经预处理可直接测定，收集样品的４个滤膜加标后测定的平均回收率为９２８％～１０８％。
The optimal separating condition and wavelength program for determination of fourteen polycyclic aromatic hydrocarbons(PAHs)in aerosol by HPLC with fluorescence detector were studied.The detection limits of PAHs are 0 90～55 19 pg.The relative standard deviations of retention time are less than 0 34%.The average spiked recoveries of PAHs in four filters collected sample varied from 92 8% to 108% .The dichloromethane extract of aerosol samples can been directly used for analysis of PAHs without pretreatment.
