Abstract：Objective To establish ultrasonic extraction/HPLC method to determine the concentrations of PAHs in PM2.5. Methods One fourth of membrane was cut into pieces, and then placed in 5 mL glass tube. In order to extract PAHs from membrane, 2.5 mL of acetonitrile was added into the tube and the tube was placed in an ultrasonic bath for 60 min. Acetonitrile and water were used as mobile phase of gradient elution. HPLC/ UV-fluorescence detector was used to detect the concentrations of PAHs. Results The range of detection limits of PAHs was 0.005~0.250 ng/m; 3. All the 16 kind of PAHs have very high recovery rates, except Naphthalene, Acenaphthene and Acenaphthylene. Conclusion The method in this study can effectively determine the concentrations of PAHs in PM2.5 and is suitable for the analysis of large numbers of samples because of its simplicity.
