电感耦合等离子体原子发射光谱(ICP-AES)法测定大理石岩型石墨矿中的酸溶铁

Determination of Acid Soluble Iron in Marble Type Graphite Ore by ICP-AES

试样经过盐酸溶解,过滤后用电感耦合等离子体原子发射光谱(ICP-AES)法测定大理岩型石墨矿中的酸溶铁。实验表明,加标回收率为99.1%,相对标准偏差(RSD)为1.0%,检出限为5μg/g,经过与标准方法分析结果对比,得到了国家标准方法一致的测定结果,但更加适用于批量样品的测定。

In th concentrations of （ICP-AES）. The was 1.0% with 5 s paper, after iron were then results showed μg/g detection obtained by the national standard of iron. the samples were determined by inductive solved by ly coupled that the recovery was 99.1%, an limit. The values determined by methods, and the proposed meth d th hydrochloric acid and filtered, the plasma atomic emission spectrometry the relative standard deviation （RSD） is method were consistent with those is more convenient for batch analysis of iron.
