摘要
本文介绍了采用火焰原子吸收光度法 ,在碳酸铵沉淀分离样液后 ,将燃烧器旋转 90°,使光束垂直穿过火焰 ,在选定的工作条件下 ,无需使用价格昂贵的消电离剂硝酸铯 ,即可准确、快速、简便地测定出样品中常量钾、钠的方法。本方法极大地扩展了原子吸收分光光度法测定钾、钠的范围 ,节约了生产成本 。
This paper presents a simple, rapid, accurate mechod that constant content of potassium and sodium is determined by flame atomic absorption spectromery under the optium condition of determination without expensive CsNO 3, turning the burner 90° after being precipitated by (NH 4) 2CO 3. The method not only expends the range of determination of potassium and sodium for FAAS, but also reduces cost of analysis, instead of flame spectromery in the pocess of testing.
