摘要
目的:为减少实验误差,提高检测结果精确度,评定水中氯化物的不确定度。方法:分析水中氯化物不确定度的来源,通过计算得出该法测定水中氯化物的扩展不确定度。结果:测量结果表明扩展不确定度U95=0.54mg/L,适用于每个水样的检测结果。结论:该方法简便,适合于每一个样本的检测结果,可参考用于水中某些检测参数的不确定评定。
Objective ： To evaluate the uncertainty of measuring Cl-concentration in drinking water.This study was to decrease experimental error and increase the accuracy of results.Methods： The source of Measurement uncertainty of the chloride determination in water was analyzed and assessment on uncertainty of chloride determination in water was calculated.Results： The result showed that the expanded uncertainty was 0.54mg/L and the method was fit for the same kind of the samples.Conclusion： The method was easy and fit for various samples and the method was for reference to assessment on uncertainty of others parameters determination in water.
