硫酸铈滴定法测定铅阳极泥中锑的测量不确定度评定

Evaluation of Uncertainty on the Determination of Antimony in Lead Anode Mud by Cericsulfate Titration

本文采用硫酸铈滴定法测定铅阳极泥中锑的含量,并对引起测量结果的不确定度分量进行评定,计算合成不确定度和扩展不确定度,找出引起不确定度的主要来源,减少测量误差,保证测量结果准确,有利于指导生产。

The determination of antimony in lead anode mud was carried out by cericsulfate titration, and the uncertainty of the determination method was analyzed. The compound uncertainty and expanded uncertainty were calculated to find out the main sources for the uncertainties, in order to reduce the measurement error and ensure the measurement accuracy.
