| Abstract: | The properties of carbonized fibrous resins as an adsorbent of polycyclic aromatic hydrocarbons(PAHs) from ambient air are reported. The sample pretreatment conditions for ultrasonic extraction and subsequent elution through a slilica _ gel column have been studied. Pretreated samples can then be analyzed by GC-MS. Results of real samples collected at some typical sites indicate that the carbonized fibrous resin is a good sorbent with unique properties. The proposed sampling method for ambient PAHs has been proved to be reliable, and can be used for PAHs determination in atmospheric environment. |
