| 目前国内外没有以稀散元素锗、铟为特征元素的矿石标准物质, 为了满足我国地质找矿的需求, 本文采集广东省韶关凡口铅锌矿作为锗矿石候选物, 广西南丹铜坑铅锌矿作为铟矿石候选物, 依据国家一级标准物质技术规范, 由10家实验室采用化学分析方法和现代仪器分析方法协作定值, 研制了1种锗矿石标准物质(GBW07831)和1种铟矿石标准物质(GBW07833)。锗矿石标准物质定值组分为45项, 铟矿石标准物质定值组分为47项, 包括特征元素、共存元素、稀土元素(15项)、造岩元素和痕量元素, 其中锗矿石中锗含量为21.6×10-6, 铟矿石中铟含量为39.7×10-6。研制的两种标准物质丰富了我国矿石标准物质的种类, 可用于锗、铟矿石化学成分分析测试的量值标准和日常质量监控。 |
| 英文摘要: |
| There are no ore standard materials which are characterized by the dispersed elements germanium and indium. In order to meet the need of geological exploration, Pb-Zn ores from Fankou of Guangdong were used as the candidates of Ge-ores and Pb-Zn ores from Tongkeng, Nandan of Guangxi were used as the candidates of In-ores. According to Class A standard material specifications, germanium ore (GBW07831) and indium ore (GBW07833) were prepared by ten laboratories using different analysis methods. Germanium ore standard contains certified values of 45 elements, whereas In-ore standard contains certified values of 47 elements. These elements include characteristic elements, coexisting elements, 15 rare earth elements, rock-forming elements and trace elements. The contents of Ge and In are 21.6×10-6 and 39.7×10-6, respectively in the germanium and indium ores. The two standard materials extend the types of ore standard material in China, which can be used as a chemical composition standard for Ge and In ores and used in daily quality control. |
