摘　　要：针对固体废物的分布不均匀性、组分复杂、形态多变等特性,以及我国的固体废物环境管理和监测框架体系,文章使用硫酸硝酸法、醋酸缓冲溶液法、水平振荡法对固体废物进行浸出前处理,同时使用微波消解、王水浴进行全量消解。使用双道原子荧光分光光度计测试浸出液和全量消解液中汞和砷元素,对比分析不同的处理方法得出不同的结果。In view of the uneven distribution of solid waste,such as complicated composition,morphology and changeful feature,and the framework of solid waste environmental management and monitoring system in our country,the article use level of sulfuric acid nitric acid,acetic acid buffer solution,oscillation method to leaching pretreatment of solid waste,at the same time using microwave digestion,aqua regia bath for the whole amount digestion.Mercury and arsenic in leach solution and total solution were measured by double channel atomic fluorescence spectrophotometer.
