本文利用端视电感耦合等离子体发射光谱建立了一种钠和钾的分析测定方法 ,优化了分析测试条件 ,方法对钠和钾氧化物的检出限分别为 0 .0 0 5和 0 .0 0 2μg/ m L ,将该方法用于保温材料中钠和钾的分析测定 ,获得了令人较为满意的结果。

One method for the determination of sodium and potassium by axially viewed inductively coupled plasma atom emission spectroscopy (ICP AES) was reported.The operational conditions were optimized with experiments. The detection limits were reached to 0.005 and 0.002ppm for sodium oxide and potassium oxide, respectively.The method was applied to analyze sodium and potassium in three kinds of heat preservation materials with satisfactory results.
