混凝土用水氯离子测定的不确定度评定

Uncertainty estimation of chlorion detection of concrete water content

采用硝酸银滴定法测定混凝土用水中氯离子浓度,对测量过程中的不确定度进行了分析和评定,结果表明:在各分量中,移液管及滴定管产生的不确定度分量较大,为滴定分析实验提供了一个评定方法的参考模式。

The paper testifies the chlorion concentration in concrete water with silver nitrate titration methods,and analyzes and estimates uncertainty in measurement.Results show that the uncertainty is rather large in transfer pipette and titration pipe,which has provided a kind of reference model of evaluation method in titration experiment.
