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0.0005～0.079 8μg/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%.%The paper developed a method to determine 31 types of impurity elements contained in the high purty gold using inductively coupled plasma atomic emission spectrometric method after the gold has been extracted by ethyl acetate in the same system. The determination limits of spectrometry is 0.0005～0.079 8 μg/mL. The determination limits of the method is 0.20～1.00μ/g. The recovery of standard material is 84 %～114 %, and the relative standard deviations (RSD %) are between 1.93%～6.61%.
