摘要
采用N2O-C2H2火焰原子吸收光谱法测定膨胀合金中硅．建立了硅的最佳测定条件，并在样品测定中对干扰因素进行了综合考虑．实验表明。该方法具有灵敏度高、选择性好，操作简便、容易掌握、分析周期短等优点．其相对标准偏差均小于1．0%（n=6）．标准加入回收率均为97．0%～99．0%（n=6）范围内．可以作为检测膨胀合金中硅含量的一种手段．
The application of N2O-C2H2 flame Atomic absorption spectrometer to measure of silicon in the alloy expands is studied. This paper introduces the optimum measuring conditions for silicon and potency in which a fine liner range presents. And makes a synthetic consideration to interference factors. The method has the advantages of high sensitivity, less interference and good in selectivity and reappearance. The relative standard deviations are all less than 1.0% （n= 6）in six sample measures, and the standard adding recovery is in the range of 97. 0%-99. 0% （n= 6）, the practice shows that the method is fully suitable to measure the silicon in the alloy expands.
