摘要： 用聚氨酯类泡沫(PUF)富集回收蒸馏水、自来水与河水中的多环芳烃,方法简便,回收率高,适于现场采集各种不同类型的水样. GC/MS分析中,氘化芘在IL蒸馏水中的检出限为26ng/L;而在HPLC/FLD分析中,苯并(k)荧蒽、苯并(a)芘、二苯并(a,h)蒽、苯并(ghi)在IL蒸馏水中的检出限分别为0.86、0.51、2.1和3.0ng/L.

Abstract: The article reports the application of PUF (polyurethane foam) for PAHs sam-pling in water.The technique is found to be suitable for the sampling of PAHs and othertrace organics in different water samples.The DL(detection limit) for pyrene-d10 in 1 Lwa-ter is 26 ng/Lwhen GC/MSis used for analysis.Much lower MDLs can be achieved whenHPLC-Fluorescence is used for PAHanalysis- The observed MDLs for benzo (k)fluoran-thene, benzo (a) pyrene, dibenz (a, h) anthracene and benzo(ghi) perylene in 1 Lwater are0.86, 0.56, 2.1, 3.0 ng/Lrespectively.HPLC-Fluorescence analysis also gives very litterbackground interference by PUF.PUFsampling coupled with HPLC-fluorescence analysis isthere fore promising method for the measurement of ultratrace levels of PAHs in aquatic envi-ronment.

Key words: PUF, Solid-phase extraction, Water analysis, PAHs
