热液铀矿(火山岩型)成分分析标准物质的研制

Preparation of Certified Reference Materials for Hydrothermal Uranium Ore-Field Component Analysis

  • 摘要: 研制了10种热液铀矿(火山岩型)成分标准物质,对每种热液铀矿(火山岩型)标准物质中的U、Th、Mo、Cu、Pb、Zn、Co、Ni、Cr、Na2O、CaO、FeO、Fe2O3、TiO2、P2O5、CO2、F、S等成分进行了定值,其中U的质量分数为7.33~2 583 μg/g。根据国家一级标准物质研制规范(JJG 1006-1994)和ISO导则35的要求,对10种热液铀矿(火山岩型)标准物质候选物进行均匀性和稳定性检验,其结果符合要求;对每种热液铀矿(火山岩型)标准物质候选物采用9个实验室合作定值的方法进行定值,得到定值结果和相应的不确定度。
    Abstract: 10 hydrothermal uranium ore-field(volcanic rock type) component reference materials were developed. Contents(reference values) of each hydrothermal uranium ore-field(volcanic rock type) reference materials were certified including U, Th, Mo, Cu, Pb, Zn, Co, Ni, Cr, Na2O, CaO, FeO, Fe2O3, TiO2, P2O5, CO2, F, S. The U concentration is from 7.33 μg/g to 2583 μg/g. According to the technical norm of primary reference material (JJG 1006-1994) and the requirements of ISO guide 35, the homogeneity and stability tests for the 10 hydrothermal uranium ore-field(volcanic rock type) reference materials were done. The results conform to the requirements. The content values of each hydrothermal uranium ore-field(volcanic rock type) reference materials by using nine laboratory for cooperation were certified, and the certified values and uncertainty were got. The development of hydrothermal uranium ore-field(volcanic rock type) reference materials contains uranium contents from low to high value, and also there are prospecting marks of associated elements values. It can meet the hydrothermal uranium ore-field(volcanic rock type) in the research field of the geological prospecting demand, and effectively guarantee the metrological traceability of measurement results and quality of the accurate. At the same time it fills the domestic hydrothermal uranium ore-field(volcanic rock type) component reference materials.
