An extraction capillary packed with a polyethylene terephthalate nanofiber-sheet was applied for the extraction of five water soluble polycyclic aromatic hydrocarbons (PAHs, including naphthalene (Nap), fluorene (Flu), phenanthrene (Phe), fluoranthene (Flt), and pyrene (Pyr)), in water samples. The extracted PAHs were eluted with acetonitrile, and on-line injected into a high-performance liquid chromatographic system coupled with a fluorescence detector. The limit of detections of the method for Nap, Flu, Phe, Flt, and Pyr were 1.0, 1.0, 0.2, 0.5, and 0.2 ng/mL, respectively, at a sample loading volume of 1.0 mL. The spiked recoveries of the analyte PAHs were in the range of 97.3 to 102% upon spiking the PAHs into tap water and river water samples.
