不确定度在测定生活饮用水氰化物分析中的应用

Application of uncertainty to determination of cyanide in drinking water

目的:探讨不确定度在测定生活饮用水中氰化物分析中的应用。方法:应用检测不确定度评定方法对测量结果进行不确定度分析与评定。结果:该方法测定水中氰化物的扩展不确定度为uc=0.00034mg/L。结论:为提高测定结果的准确性,减小不确定度,在检测过程中应采取一些技术改进措施。

Objective： To discuss the application of uncertainty to the determination of cyanide in drinking water. Methods： The measurement uncertainty was evaluated based on the theory of uncertainty determination. Results： The expanded standard uncertainty for the determination of cyanide in water was uc = 0.00034 mg/L. Conclusion： Some technological innovations should be made and the control on the standard curve strengthened in order to improve the accuracy of determination.
