摘要
根据方法CJ/T221-2005,建立了火焰原子吸收光谱法测定污泥中镍不确定度数学模型,分析了测试过程中不确定度的来源,并对各不确定度分量进行量化,城市污泥中镍的测定结果为37.72±2.08mg/kg,K=2,即测定结果置信水平95%。
According to the method of CJ/T 221-2005,an uncertainty mathematical model for determination of nickel in municipal sludge by flame atomic absorption spectroscopy （FAAS） was established,which the sources of uncertainty in the process of determination were analyzed,and the components of uncertainty were calculated. The determination results of nickel in municipal sludge were 37.72± 2.08mg/kg,k= 2 （confidence level of 95% ）.
