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.
