摘　　要：采用湿法消解对垃圾渗滤液样品进行预处理,通过火焰原子吸收分光光度法对生活垃圾填埋场渗滤液试样中的离子进行测定,对镉污染程度进行分析,以了解垃圾填埋场中垃圾渗滤液的镉质量浓度,为发展中城市的环境污染治理问题提供可参考的信息.采用此方法测定的垃圾渗滤液中镉质量浓度为0.011 88mg/L,远低于国家限定标准0.10mg/L.In this article,the sample of household refuse is preprocessed by means of wet digestion.Then using flame atom absorption spectrometry,the testers have determined the ions in the leachate sample which is got from a certain refuse disposal plant.In this process,testers try to make an analysis of the degree of the Cadmium pollution and find out the content of Cadmium in the refuse disposal plants.The aim of this research is to provide some reference information for some developing cities in the control of environment pollution.After testing,the tester found that the degree of the Cadmium in the household refuse is 0.011 88mg/L,which is far below the national lolerance standard of 0.01mg/L.
