EDTA溶液络合滴定法测定石灰石中氧化钙含量的不确定度评定

Evaluation of uncertainty in the determination of calcium oxide in limestone by EDTA solution complexometric titration

利用EDTA溶液络合滴定法测定石灰石中氧化钙含量,分析了氧化钙含量不确定度产生的原因,并建立相应的数学模型,而且对一个石灰石中的氧化钙含量测定结果的不确定度进行了评定。

the content of calcium oxide in limestone was determined by EDTA solution complexometric titration,the cause of uncertainty of calcium oxide content was analyzed,and the corresponding mathematical model was established,the uncertainty of the determination result of calcium oxide content in a limestone was evaluated.
