摘要
目前我国有机氯农药和有机卤化物监测标准存在的缺点为提取时间长,不利于快速分析;使用的色谱柱为填充柱,分离能力差;样品纯化方法为硫酸磺化法,该方法会使一些有机氯农药(如狄氏剂、异狄氏剂等)在纯化过程中降解。介绍了现有国标法中存在的一些问题,以及国内外在该领域的一些最新研究成果。
At present in our country the organic chlorine agricultural chemicals and the organic halide monitor standard exists shortcoming with long extraction time.The use chromatographic column for fills the column,separation ability was bad.The sample purification method for the sulfuric acid sulphur reduction can cause some organic chlorine agricultural chemicals（for example dieldrin,different dieldrin and so on） todegrade in the purification process.In this article some questions in the introduction existing GB code law,as well as some newest research results were introduced.
