ActiveMethods for chemical analysis of crude gold - Part 4: Determination of lead content - EDTA titrimetric method
合质金化学分析方法 第4部分：铅量的测定 EDTA滴定法
Application Summary AI generated
This standard specifies the EDTA titrimetric method for determining lead content in crude gold, which is unrefined gold containing various impurities. It is applied in the metallurgical industry, specifically for quality control and material characterization during the processing and trading of crude gold, such as in gold mines, smelters, and recycling facilities. The method ensures accurate lead quantification to assess gold purity and meet regulatory or commercial specifications.
