摘要
介绍了重铬酸钾滴定法测定Fe O含量的试验方法,对包括测试过程中的一些滴定条件、试剂及防氧化措施进行了详细讲解,着重分析了其关键影响因素,并对试验条件及装置进行了优化,提高了该方法在实际检测过程中的操作性及准确性。
A method for the determination of ferrous content in iron ore by potassium dichromate titrimetric method was introduced in the paper. The titration conditions, reagent and oxidation inhibition method were studied, the key influence factors were analysised, the experimental conditions and facility were optimized. As a result, the convenience and accuracy of the experiment were improved.
