铁基样品中锰的中子活化法测定

Determination of Manganese in Iron Matrix Materials by Neutron Activation

采用热中子与超热中子照射相结合的中子活化法测定了铁高含量样品中锰的含量。实验测定和理论计算了铁对锰的干扰系数，两者符合较好。对几个标准物质的分析结果与推荐值相符。

A new neutron activation method based on thermal and epithermal neutron irradiation was established to determine manganese in iron matrix materials. The interference coefficients of iron to manganese was determined and calculated theoretically. Some pure iron standard reference materials were analyzed and the results were in an agreement with certified values. This method was suitable for the determination of manganese in samples with content ratio of m Fe / m Mn lower than 2×10 5.
