库仑滴定法测定煤炭中全硫的不确定度分析

Evaluation on uncertainty of determination of total sulfur using coulometric titration method

本文根据GB/T214-2007标准介绍库仑滴定法测定煤炭中全硫含量及不确定度来源,包括由于各种因素产生的不确定分量进行了分析和合成,从而得出不确定的主要来源,同时对检测结果不确定度进行评定。通过测量全硫含量及不确定度数据分析,对企业生产具有引导作用。

According to the standard of GB /T214- 2007,this paper introduces how to use the method of coulometric titration to determine total sulfur content and other uncertainty component in coal. It includes the analysis and synthesis of the uncertainty component caused by various factors,showing the main source of uncertainty,and the evaluation of uncertainty to the detection results. The standard plays a leading role through the measurement of total sulfur content and the analysis of the data of uncertainty.
