摘要：

The determination of mono- and di-nitro polycyclic aromatic hydrocarbons (PAHs) was accomplished by on-line reduction to the corresponding amino PAHs, which were then separated and detected using high-performance liquid chromatography (HPLC) and chemiluminescence detection. The on-line reduction was carried out in a methanol-water mobile phase by the use of a catalyst column packed with material originating from a grained automobile three-way catalyst. HPLC separation was completed with acetonitrile-buffer mobile phase at pH = 7.5. Bis(2,4,6-trichlorophenyl) oxalate and hydrogen peroxide was used as the reagent for chemiluminescence detection. The detection limits for some mono- and di-nitro PAHs were in the range of 1 to 10 picogram. The developed method was demonstrated on samples originating from diesel exhaust particle material extracts.
