摘要
以乙酸乙酯为萃取剂萃取分离高纯金中的杂质,采用电感耦合等离子体发射光谱仪测定其含量,并对萃取过程、测定方法及仪器条件进行了研究.测得被测杂质元素的检出限为0.00002%~0.00010%,回收率为93.1%~107.7%,相对标准偏差小于4%,结果令人满意.

Abstract:
The paper developed a method of determining impurity elements contained in the gold by using inductively coupled plasma emission spectrometric method(ICP-OES),after the gold had been extracted with ethyl acetate as exeractant.A detailed description of the extraction process and determination methods were made.The detection limit was between 0.00002% and 0.00010%,the recovery rate of them was in the range of 93.1%~107.7%,and the relative standard deviation was less than 4%.The results were satisfiable.
