火花光谱法测定粉末样品中的高含量硅

The Determination of High Content Silicon in Powder Samples by Spark Spectrometry

利用火花光谱法定量检测了硅铋样品中质量分数为３０％的元素硅，分析结果表明，相对误差不大于８．４％，相对标准偏差为５．９％，方法是简便可行的。

The quantitative determination of 30% silicon in silicon-bismuth samples is perfoumed by spark spectrometry. The analytical results show that the relative error is less than 8.4%, the relative standard deviation is 5.9%. The method is practicable.
