国家金矿石标准物质定值分析

摘要

2006年武警黄金指挥部测试中心参加了4个国家金矿石一级标准物质(GBW 07807GBW 07810)定值测试工作,采用碘童法测定溶液中的金与原子吸收测定残渣中的金相结合的方法,分析结果均被采用.%In 2006, Testing Center of Gold Geological Institute, CAPF, joined the value testing of 4 gold ore samples of National Certified Reference Materials. Gold in solution was determined by iodimetry and gold in residue was determined by atomic absorption spectrophotometry. All of the four results were adopted by Institute of Geophysical and Geochemical Exploration, Chinese Academy of Geological Sciences.
