中文摘要：

建立了超高效液相色谱系统(UPLC)荧光检测土壤中15种美国环境保护署(USEPA)优控的多环芳烃(PAHs),简化了土壤样品中PAHs的前处理过程。UPLC对15种PAHs分离时间为17 min,流速为0.4 mL/min。荧光检测器对15种PAHs的检出限为0.03~1.53μg/L,6次重复测定的峰面积相对标准偏差为0.12%~0.99%。除了萘和苊外,土样加标的平均回收率为82.9%~103.4%。由于色谱柱的较高分辨率以及荧光检测器的较高选择性,在定性和定量研究土壤样品中的PAHs时,提取物的硅胶柱净化步骤可以省略。

英文摘要：

A method for the determination of the 15 USEPA priority PAHs in soil by ultra performance liquid chromatography(UPLC) with a fluorescence detector was established and the pretreatment procedure for the detection of PAHs in soil was simplified.The results showed that the characteristics of the method were high speed(17 min) and low flow rate(0.4 mL/min).The limits of detection for 15 PAHs with the fluorescence detector ranged from 0.03 μg/L to 1.53 μg/L and the relative standard deviations of the peak areas ...
