ActiveMethods for chemical analysis of high - purity gold - Part 3: Ethylether extraction separation - Inductively coupled plasma-atomic emission spectrometry - Determinaion of impurity elements contents
高纯金化学分析方法 第3部分：乙醚萃取分离ICP-AES法 测定杂质元素的含量
Application Summary AI generated
This standard specifies the use of ethyl ether extraction separation combined with inductively coupled plasma-atomic emission spectrometry (ICP-AES) to determine the content of impurity elements in high-purity gold. It is applied in the metallurgical industry for quality control and certification of high-purity gold products, particularly in refining, jewelry manufacturing, and precious metal trading. The method ensures accurate detection of trace impurities to meet purity specifications for industrial and investment-grade gold.
