研究并建立了在同一体系中经溶剂萃取后用电感耦合等离子体发射光谱测定高纯金中31种杂质元素的方法。仪器检测限为0.0005~0.0798μg/mL,方法检测限为0.2~1.0μg/g,加入标准物质回收率为84%~114%,分析精密度为1.93%~6.61%。
A method for the determination of 31 kinds of impurity elements in high purity gold by ICP-AES after solvent extraction in the same system was established and established. The detection limit was 0.0005 ~ 0.0798μg / mL. The detection limit of the method was 0.2 ~ 1.0μg / g. The standard recoveries were 84% ~ 114%. The analytical precision was 1.93% ~ 6.61%.
