摘要
采用重铬酸钾容量法测定硼镁矿石中的氧化亚铁含量,分析测定过程中产生的各项不确定度,并对产生的不确定度进行评定,从而得出环境温度以及容量瓶等定量用具的精密性是影响该方法测定结果准确性的主要因素。
The content of ferrous oxide in boric magnesium ore were determined by potassium dichromate volumetric method. The uncertainty of determination of process were analysed and evaluated. The main sources of uncertainty were analyzed, including the uncertainty of the environment temperature and volumetric flask.
