铁矿石中一般不含Cr、Ni两种元素,即使有也非常微量。本文探索用过氧化钠熔融,运用标准系列绘制标准曲线,ICP等离子发射光谱仪同时测定矿石中Cr、Ni两种元素的方法,取得较好的效果,该方法用于样品测定,结果满意。
Iron ore generally does not contain Cr, Ni two kinds of elements, even if there are very trace. In this paper, the method of simultaneous determination of Cr and Ni in ore by sodium silicate melting and standard curve drawing and ICP plasma emission spectrometer was explored. The method was applied to the determination of samples with satisfactory results.
