Description

一种串联紫外荧光检测器测定16种多环芳烃的方法
技术领域:
本发明涉及一种串联紫外荧光检测器测定16种多环芳烃的方法,属于环境监测技术领域。
背景技术:
多环芳烃(PAHs)是指分子中含有两个或两个以上苯环结构的化合物,是煤、石油、煤焦油等有机化合物的热解或不完全燃烧产物,具有致畸、致癌、致突变和生物难降解的特性。因此对于土壤、水和空气中的多环芳烃的测定具有非常重要的意义,现有的多环芳烃的监测技术:主要有气相色谱 ( G C)法、高效液相色谱 ( H P LC)法 和气相色谱-质谱联用法。气相色谱 (GC)法:流动相位惰性气体,由于PAHs化学性质相近且沸点较高,采用气相色谱来分析高沸点的PAHs存在一定困难,主要原因是分析温度已接近所使用分析柱、色谱炉的极限温度 ,缩短了分析柱和仪器使用寿命;高效液相色谱 (HPLC)法:流动相为液体,如乙腈、水。能分析高沸点、热稳定性差的有机化合物,在多环芳烃、苯胺类以及残留的有机农药分析方面得到越来越广泛的应用;气质法(GC/MS):质谱作为气相色谱的“检测器”,能检出几乎全部化合物,气相色谱法无法完全分开的组分经电离后再按质荷比作进一步分离,测量过程较为复杂。
发明内容:
本发明的目的是针对上述存在的问题提供一种串联紫外荧光检测器测定16种多环芳烃的方法,能够在23分钟内快速检测出16种多环芳烃,与国家标准方法相比,明显缩短了样品的分析时间。
