摘要
根据HJ 491-2009火焰原子吸收分光光度法测定土壤中的总铬,分析了各不确定度分量的来源,以某一土壤样品为例,对各不确定度分量进行了计算,最终得出扩展不确定度结果。
Determination of total chromium in soil by flame atomic absorption spectrometry based on HJ 491-2009, the sources of the uncertainty components were analyzed. Take a soil sample as an example, the components of the uncertainty were calculated, then the result of expanding uncertainty was gained.
