摘    要:采用硫氰酸铵容量法测定水泥中氯离子含量,对其进行不确定度评定。建立数学模型,量化分析了不确定度分量测量重复性、滴定时消耗标准滴定液体积、试样质量等参数,计算合成不确定度并提出在实验过程中怎样减少不确定度。

关 键 词:硫氰酸铵  氯离子  测量不确定度  评定

Abstract:The chloride ion content in cement was mensurated by ammonium theiocyanate volumetric method, and the uncertainty was evaluated. And mathematical model was established to analyse quantitively several parameters as measurement repeatability of uncertainty components, standard titration solution volume consumption and sample mass etc, the combined uncertainty was calculated and method to reduce uncertainty in experiment was put forward.
Keywords:ammonium thiocyanate   chloride ion   uncertainty measurement   evaluation
