固体废物浸出液中挥发性有机物测定方法

Determination Method of Volatile Organic Compounds in Solid Waste Leachate

由于固体废物浸出液中的挥发性有机物可能会给人体带来巨大危害。为了解决挥发性有机物带来的影响,提出固体废物浸出液中挥发性有机物测定方法。方法首先利用吹脱捕集技术对固体废物浸出液中挥发性有机物的标样定量进行有效分析,通过吹扫捕集-气相色谱-质谱联用及内标法定量两种方法对挥发性有机物分析结果中的化合物进行测定,并在此基础上分析了实际挥发性有机物样品对不同地区带来的影响。结果表明,上述方法为解决固体废物浸出液中挥发性有机物给人类生活环境造成危害问题提供了重要的信息依据。

The volatile organic compounds in solid waste leachate may lead to great harm to the human body.In order to reduce the impact of volatile organic compounds,a method for determining volatile organic compounds in solid waste leachate was presented.At first,this method used the purge-trap technology to effectively analyze the quantity of standard samples of the volatile organic compounds in solid waste leachate.And then the compounds in the analysis results were determined by the purge and trap-gas chromatography-mass spectrometry and the internal standard method.On this basis,the influence of actual samples of volatile organic compounds on different regions was analyzed.The results prove that this method provides an important information basis for solving the problem of harm caused by volatile organic compounds in solid waste leachate to the living environment.
