本文介绍了测定纯金中硅的四种方法。这四种方法是用水溶液校正标准的固体试样电热原子吸收光谱法（ＥＴＡＡＳ）；采用基体－致标准的ＥＴＡＡＳ溶液法；采用基体一致标准的电感偶合等离子体原子发射光谱法（ＩＣＰ－ＡＥＳ）和火花采样ＩＣＰ－ＡＥＳ法。前三种方法提供可比结果，但固体试样ＥＴＡＡＳ法容易造成误差。由这些方法得出的结果用于金的参照物质特征化．这些物质用作火花采样ＩＣＰ－ＡＥＳ法测定金中硅含量时的校正标准。采用这些方法．检测限为３μｇ／ｇ或更好。
This article describes four methods for determining silicon in pure gold. These four methods are calibrated with an aqueous solution of a standard solid-phase sample by electrothermal atomic absorption spectroscopy (ETAAS), using a matrix-to-standard ETAAS solution method, inductively coupled plasma atomic emission spectrometry (ICP-AES) And spark sampling ICP-AES method. The first three methods provide comparable results, but the solid sample ETAAS method is prone to error. The results from these methods are used to characterize gold reference materials. These materials are used as a calibration standard for the determination of silicon in gold by spark-based ICP-AES. Using these methods. The detection limit is 3 μg / g or better.
