对石墨炉原子吸收法测定纯铁高温合金中铜进行了研究,在不分离的情况下直接测定铜、银,取得满意结果。此方法灵敏简便,受基体干扰程度小,适于纯铁高温合金中微量铜、银的测定。测定范围下限0 .0 0 0 1%。
The graphite furnace atomic absorption method was applied to the determination of copper in pure iron superalloy. Copper and silver were directly measured without separation. Satisfactory results were obtained. This method is sensitive and simple, less interference by the matrix, suitable for determination of trace copper and silver in pure iron superalloy. The lower limit of measurement range 0. 0 0 0 1%.
