摘　　要：通过水平震荡法,以一级纯水为浸提剂,对固体废物进行浸出,模拟填埋地下的固体废物受到地下水的浸沥,利用电感耦合等离子体发射光谱法测定进入环境中总镉含量。探讨了该方法的不确定度来源,分析影响不确定度的主要因子,最终通过建立数学模型,评定此方法的不确定度,从而判断利用该方法测定得到的固体废物总镉浸出数据的可信赖程度。Solid wastes are leached by horizontal vibration with first-grade pure water as the leaching agent,simulating the scenario of landfilled solid wastes subject to groundwater leaching.Total cadmium content leached into the environment is measured by inductively coupled plasma emission spectrometry.The paper discusses the sources of uncertainty in this method,analyzes the main factors affecting the uncertainty,and finally stablishes a mathematical model to evaluate the uncertainty of this method.In this way,it helps to judge the degree of trustworthiness of obtained total cadmium leaching data for solid wastes by using this method.
