摘要
指出了多氯联苯是一种持久性环境污染物,地表水中PCBs液液萃取气相色谱法分析技术具有相当的代表性,以EPA的标准分析方法为基础,结合多年实验经验,对此方法内容进行了详细描述并对部分内容进行了优化,旨在为该方法的转化研究提供一些参考。
Polychlorinated biphenyl （PCBs） is a persistent environmental pollutant. The technique of liquid-liquid extraction and gas chromatography analysis for determining PCBs in surface water has a considerable representativeness. On the basis of standard analytical methods of EPA and combing with many years of experimental experiences,the article gives a detailed description of the method and the content and optimizes some parts of them,which aim to provide some references for the researches on the conversion of the methods.
