摘要
在分析矿石中全铁含量时,其中原矿的FeO含量也需要进行测定。对采用"重铬酸钾滴定法"测定FeO含量时,称样重量与其结果准确度的关系问题、溶样过程中应注意的事项、滴定管调零时重铬酸钾标液的排放等问题进行了探讨。
It is necessary to determine the content of FeO in raw ore when analyzing the full iron content in iron ore.It is discussed the relation between sample weight and result accuracy,matters needing attention in sample dissolving,discharge of standard solution of potassium dichromate when titration-tube zero-adjusting in determination of content of FeO with ＂potassium dichromate titration＂.
