| 摘 要： | 本文研究了ICP-AES法测定铁矿中铝,钙、镁、锰、钴、铜、钠和钾的方法。对仪器工作参数,共存元素的光谱干扰和基体效应干扰进行了探讨。采用向标准系列中加入铁基空白溶液建立工作曲线,试样经酸处理后即可直接测定。本方法获得了良好的回收率(95～103%)和变异系数(0.5～1.3%,n=11),同原子吸收法进行比对试验,结果一致。

| Abstract: | This paper descrides a method for determination of Al, Ca, Mg, Mn, Co, Cu,Na, K in iron ore by ICP-AES. Parameters of instrument and interferences of coexisted elements and matrix effect were discussed. Iron base solution was added into standard series to prepare working curve. Analysis can be performed after dissolving the sample in acid. The precision of the assay (CV)was 0.5-1.3% (n=11). The recovery was 95-103%. Satisfactory results were obtained in comparison with AAS. |
