滴定法测定铁矿中氧化亚铁的不确定度评定

Assessment on uncertainness of ferrous oxide in iron ore measured by method of determination by titration

讨论和比较重铬酸钾滴定法测定铁矿(烧结矿)中氧化亚铁的各种不确定度因素,并评定氧化亚铁的测量不确定度。

The present paper discusses and compares the various uncertain factors in measurement of the content of the ferrous oxide in the iron ore （sintered ore） by the method of determination by titration of potassium bichromate（K2Cr2O7 ）and assesses the uncertainness in determination of the ferrous oxide.
