| Abstract: | This paper refers to a new simple constant-energy synchronous fluorimetric method used to determine multi-component polycyclic aromatic hydrocarbons in the mixture of micellar solution(SDS),which can realize the identification and measurement of as many as 11 components in the solution simultaneously without any pretreatment viz.separation of the mixture.It is reported that the range of detection limits was 1.3×1011～4.4×10-9 g/mL;range of standard deviations was 1.03～1.73,the recovery 77.88%～120.13% when analyzing river water and 62.36%～123.56% when analyzing wastewater. |
