| 摘 要： | 通过选择合适的能量差(Δ-υ=1 400 cm-1),建立了大气漂尘中苯并a]芘的恒能量同步荧光分析法。苯并a]芘在甲醇与十二烷基磺酸钠(SDS)溶液中均有良好的线性关系(R>0.999),检出限分别达到1.34 nmol/L与0.40 nmol/L。该法亦可应用于18种多环芳烃混合物中苯并a]芘的鉴别。

| Abstract: | A sensitive analytical method using constant-energy synchronous fluorimetry for selective determination of benzoa]pyrene(BaP) in airborne particulates(AP) has been developed.A constant-energy difference of 1 400 cm-1 was selected for obtaining single spectral peak.The method could easily identify BaP in an 18-component PAH mixtures.Calibration plots in methanol solution and in sodium dodecylsulfate(SDS) micellar media shows a good linearity(R>0.999) in the BaP concentration range generally found in the environment.The detection limits of the method were 0.40 nmol/L in SDS micellar medium and 1.34 nmol/L in methanol solution,respectively. |
