| Abstract: | The PAHs(polycyclic aromatic hydrocarbon) in the atmospheric particles were extracted by supersonic and analyzed directly by constant-energy synchronous fluorescence spectrometry.The sample pretreatment process was less laborious and the accuracies of the qualitative and quantitative results were improved.The calibration curves of the PAHs were linear in three orders of magnitude with an average correlation coefficient of 0.999 1.The detection limits ranged from 0.013 ng to 4.4 ng and the average recoveries ranged from 80% to 132%.The method has been applied to the determination of PAHs collected from three monitoring stations. |
