| 摘 要： | Polycyclic aromatic hydrocarbons(PAHs)are important environmental pollutions originating from a wide variety of natural and anthropogenic sources.Benzoa]pyrene is frequently sought as an indicator of the presence of other PAHs.Fluorescence spectrometry serves as a good technique to analyze PAHs with high sensitivity.However,this technique is unfavorable for the analysis of benzoa]pyrene in multi-component PAHs because of spectral overlap.This complication can be simplified by using spec…

| Abstract: | Constant-energy synchronous fluorimetry was used for the identification of benzoa]pyrene in mixtures with a detection limit of 1.34 nmol/L. The recovery experiments in cigarette smoke samples have also obtained satisfactory results of 99.1-103.5% for benzoa]pyrene. |
