| Abstract: | The HPLC-MS method for the determination of Nitro-Polycyclic Aromatic Hydrocarbons （Nitro- PAHs） in Total Suspended Particle （TSP） of urban atmosphere, using Methanol and Dichloro Methane as solvent for the ultrasonic extraction of particle sample, has been established. The HPLC condition is shown as follows： reversed-phase C18 column, methanol： water as mobile phase, flow velocity of 0.6 mL/min, UV wavelength for detection： 254 nm. Results of this work showed that there are selever Nitro-PAHs was found in air particulate ： 2-nitrofluorene, 9-nitroanthracene, 3-nitroperylene, 7-nitrobenza]anthracene, contents of Nitro-PAHs were in ranges of 0.2-25 μg/mL. |
