摘　　要：铬铁矿采用过氧化钠熔融分解,盐酸酸化,在标准溶液中加入与待测液相匹配的基体,电感耦合等离子体发射光谱法测定矿样中的三氧化二铬,方法用于分析国家一级标准物质,分析结果与标准值一致,均在误差允许范围内;与传统的容量法、光度法相比,分析速度快,流程短,准确度高。Chromite is decompositied by sodium peroxide and acidificated byhydrochloric acid, adding the same sample blank to the standard solution to make the same base with the sample.Analysis the chromites of the country standard by this way - Inductively Coupled Plasma-Atomic Emission Spectrometry. The results are consistencies with the standard samples.By this way we can get the results quickly and accurately compared with tiaditional methods.
