- 中文摘要: This paper presents a trisolvent ultrasonic extraction and HPLC analysis method for the determination of 11 polycyclic aromatic hydrocarbons in air particulate collected on an air filter by a commercial high volume air sampler. A reverse phase column , Vydac 201 TP, and a gradient mobile phase, acetonitrile/water, were used. The 11 PAHs, fluoranthene, pyrene, benz〔a〕anthracene, chrysene, benzo〔b〕fluoranthene, benzo 〔k〕fluoranthene, benzo〔a〕pyrene, dibenz〔a,h〕anthracene, benzo〔ghi〕 perylene, indeno〔1,2,3-cd〕pyrene, and coronene were completely resolved under experimental conditions. All the PAHs except coronene were monitored by fluorescence with.lambda./sub ex/=270nm, .lambda./sub em/>389nm. Coronene was monitored by UV with .lambda.=300nm. The methodology was evaluated by spiking SRM 1649 with a PAH standard and then going through different extraction procedures and analyzing the PAH concentrations without clean-up. An external standard method was used for quantitation . The recovery yields for fluoranthene, benz〔a〕anthracene, benzo〔a〕 pyrene, benzo〔ghi〕perylene and indeno〔1,2,3-cd〕 pyrene were above 90%. The detection limits of PAH with fluorescence at .lambda./sub ex/=270nm, .lambda./sub em/>389nm ranged from 5.7pg to 69.5 pg.
