铂族元素分析一直是地质材料分析中最棘手的任务之一,是铂族金属矿产资源勘查、评价和相关研究工作的瓶颈.铂族元素标准物质作为铂族元素分析的计量标准,在分析质量监控、分析仪器校准、分析方法评价和仲裁分析中发挥着重要作用.笔者等评介了我国研制的超基性岩和铬铁矿铂族元素标准物质、铂族元素地球化学标准物质、铂族元素矿石标准物质和海山富钴结壳铂族元素标准物质共4个系列21个标准物质,也给出了其他地球化学标准物质中铂族元素的定值数据;并与南非、加拿大、俄罗斯和岩石矿物分析标准国际工作组研制的13个铂族元素标准物质及其他国际地球化学标准物质中铂族元素的数据进行了对比.这些标准物质的研制与应用将大大提高铂族元素分析数据的可靠性,为我国和世界铂族金属矿产资源勘查、评价及研究提供了有力的技术支撑.

The analysis of platinum group elements (PGEs) is one of the most challenging tasks in geoanalysis. It is also the bottleneck for the investigation, evaluation and related research of PGEs minerals and natural resources. As metrology standards, PGEs reference materials play important roles in the quality control of geoanalysis,the calibration of analytical instruments, the assessment of analytical methods and the arbitration analysis. In this paper, we review all certified values of PGEs in four series, totaling 21, of PGEs reference materials (ultrabasic rocks and chromite ores PGEs reference materials, geochemical PGEs reference materials, ores PGEs reference materials and Co-rich seamount crust PGEs reference materials)and other geochemical reference materials prepared by China. Furthermore, the comparisons with PGEs reference materials and certified values of PGEs in other geochemical reference materials prepared by other countries (e.g. South Africa, Canada, Russia and the G roupe I nternational de T racail-I nternational W orking G roup) are presented. It is outlined that the preparation and application of those PGEs reference materials will contribute to an improvement of the reliability of the analytical results for PGEs in general, and to a rational investigation, evaluation and research of PGEs mineral and resources at last.
