Abstract
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.
The article reports the application of PUF (polyurethane foam) for PAHs sampling in water. The technique is found to be suitable for the sampling of PAHs and other trace organics in different water samples. The DL(detection limit) for pyrene-d10 in 1 L water is 26 ng/L when GC/MS is used for analysis. Much lower MDLs can be achieved when HPLC-Fluorescence is used for PAH analysis. The observed MDLs for benzo (k) fluoranthene, benzo (a) pyrene, dibenz (a, h) anthracene and benzo (ghi) perylene in 1 L water are 0.86, 0.56, 2.1, 3.0 ng/L respectively. HPLC-Fluorescence analysis also gives very litter background interference by PUF. PUF sampling coupled with HPLC-fluorescence analysis is therefore promising method for the measurement of ultratrace levels of PAHs in aquatic environment.
