在目前已发现的450多种致癌物质中有200多种为多环芳烃(PAH)。水中多环芳烃的分析对于水的监测和治理十分重要,在这方面国外已进行了很多研究。我国对PAH的分析多以3,4苯并芘为代表,大多采用纸层荧光法。这种方法设备虽简单,但能分离的组分单一,操作费时。高速液相色谱法具有分离能力强,操作简单以及与荧光光度计联用时的高灵敏度、高 More than 200 of the more than 450 carcinogens found so far are polycyclic aromatic hydrocarbons (PAHs). Analysis of PAHs in water is very important for the monitoring and treatment of water, and many studies have been conducted abroad in this area. Analysis of China’s PAH mostly 3,4-benzopyrene, mostly paper fluorescence method. This method is simple equipment, but can separate a single component, the operation time-consuming. High-speed liquid chromatography has the ability to separate, easy to operate and with the fluorophotometer when combined with high sensitivity, high
