| 摘 要： | 本文介绍了氰化亚金钾中金含量及杂质的测定方法。本文采用湿法重量法测定金含量，滤液经富集浓缩后，采用火焰原子吸收法测定杂质，无需二次溶样。结果表明，该方法对氰化亚金钾样品中的Au、Ag、Cu、Pb、Fe、Co、Ni、Zn和Cr等元素的分析具有一定的准确度和精密度。金的相对标准偏差小于0．5％，杂质元素的相对标准偏差小于3％，回收率介于95％～105％之间。

| Abstract: | This paper introduces gold content and impurities content determination method in potassium aurocyanide. The gold content determined by wet-gravimetric method. The filtrate was concentrated by the concentration, determined impurities by FAAS, without secondary dissolving. The results show that the analysis method was high accuracy and precision for determined Au, Ag, Cu, Pb, Fe, Co, Ni, Zn and Cr in potassium aurocyanide. The relative standard deviation of gold is less than 0.5%, of impurities less than 3%, and recoveries ranged of impurities from 95% to 105%. |
