| Abstract: | Objective To establish a method for evaluating lead content uncertainty in water samples by flame atomic absorption spectrometry. Methods According to national standards（ GB/T 5750. 6 - 2006）, the mathematical model of uncertainty was stablished, and composed of uncertainty was analyzed and calculated. Results When the external control of lead content in water was 1.29 mg/L, the expanded uncertainty was 0. 06 mg/L（k = 2）. Conclusion This method can be applied to assess lead content uncertainty in water samples by flame atomic absorption spectrometry. |
