摘    要:对原子吸收法测量垃圾焚烧飞灰毒性浸出液中铅含量的不确定度进行评定。分析了测定过程中不确定度来源主要包括分析过程中使用的玻璃器皿﹑标准溶液﹑标准曲线﹑试液定容体积﹑样品消解及测量重复性等引入的不确定度分量。建立了数学模型,并计算了各标准不确定度分量、合成标准不确定度、扩展不确定度,得出了影响测定结果的几种重要因素。

关 键 词:原子吸收  测量不确定度  评定

Abstract:The uncertainty in detection of lead content in solid waste toxicity by atomic absorption was evaluated.The sources of uncertainty in process of detection were analyzed,including handling glassware,preparing calibration solution,curve fitting calibration curves,reagent volume,digesting samples and repeating measurement and so on.The mathematics model was established.The components of standard uncertainty,combined standard uncertainty and expanded were calculated.Some important factors affecting the measurem...
Keywords:atomic absorption  measurement of uncertainty  evaluate
