摘要
以乙腈-甲醇-水(55:20:25 pH=6.5)作为流动相对七种多环芳烃进行了分离,并利用过氧草酰类柱后反应化学发光系统对分离的化合物进行了测定。七种多环芳烃中苝的检测限最低,为2.Spg。175pg苝的变异系数为2.97%。此方法检测苝的线性范围为2.8～700pg。使用仪器是实验室自制,结构简单。应用此法对生油岩提馏物的多环芳烃样品进行了测定。
Seven polynuclear aromaric hydrocarbons were separated on a column of reversed-phaseby using a mobile phase of acetonitrile-methanol-water(55:20:25 pH=6.5) and then detectedby post-column-chemiluminescence reaction of peroxyoxalyls. The detection limit, coefficientof variation and linear respones of perylene are 2.8pg, 2.97% for 175pg and 2.8～700 pg resp-ectively.
