X射线荧光光谱法在有色金属矿石标准物质定值分析中的应用

Application of X-Ray Fluorescence Spectrometry in Analysis of Reference Nonferrous Metallic Ores

摘要: 报告了X射线荧光光谱法在铜矿、铅矿、锌矿、钨矿和钼矿标准物质定值分析中的应用。样品用低倍稀释熔融法在热解石墨坩埚中熔融,用人工标样进行校准,计算了COLA方程的理论影响系数,所有分析元素全部用理论影响系数法校正吸收-增强效应。分析结果与不同实验室不同分析方法的结果相吻合。

Abstract: X-ray fluorescence spectrometry was applied to analysis of reference copper, lead, zinc, tungsten and molybdenum ores. The samples were fused in graphite crucibles using a low dilution fusion technique. Calibration was carried out with synthetic standards
