| 中文摘要:运用导数-同步荧光光谱建立了快速同时测定溶解态菲(Phenanthrene,Phe)及其中间代谢产物1-羟基-2-萘甲酸(1-Hydroxy-2-naphthoic acid,1H2NA)的分析方法。所建方法同时测定Phe与1H2NA的线性范围分别为4.0~1.0×103 μg/L和4.0~1.2×103 μg/L，检出限分别为0.08 μg/L和0.07 μg/L，加标回收率分别为96.5%~105.3%和99.2%~106.5%，相对标准偏差均小于1.0%。该方法可应用于实验室条件下溶解态Phe微生物降解过程中Phe和1H2NA的测定，具备原位研究Phe降解过程中间代谢产物1H2NA的应用潜力。 |

| Abstract:A novel method for the simultaneous determination of dissolved phenanthrene(Phe) and its intermediate metabolite 1-hydroxy-2-naphthoic acid(1H2NA) in aqueous solution was established by using derivative synchronous fluorescence spectroscopy.The linear dynamic ranges for the determination of Phe and 1H2NA were 4.0-1.0×103 μg/L and 4.0-1.2×103 μg/L,with the detection limits of 0.08 μg/L and 0.07 μg/L,and the spiked recoveries of 96.5%-105.3%and 99.2%-106.5%,respectively.And the relatively standard deviations were less than 1.0%.The established method was successfully applied in the determination of Phe and 1H2NA during biodegradation of dissolved Phe in lab,which showed that it has a potential in in situ determination of Phe and 1H2NA. |
