建立了一种火焰原子吸收光谱法(FASS)测定玻璃中的钾、钠含量的方法。该方法对火焰原子吸收的狭缝宽度、燃烧头角度和元素的测定波长进行了优化,实验结果表明该方法测定钾含量的相对标准偏差(RSD)为3.4%~4.8%,加标回收率为95%~102%；测定钠含量的相对标准偏差(RSD)为0.8%~4.8%,加标回收率为92%~105%。

A method for the determination of potassium and sodium in glass by Flame Atomic Absorption Spectrometry(FASS) was established. In this method, the slit width of FASS, the angle of combustion head and the determination wavelength of elements were optimized. The experimental results show that the RSD of potassium content determined by this method is 3.4%~4.8%, and the recovery rate is 95%~102%; the RSD of sodium content determined by this method is 0.8%~4.8%, and the recovery rate is 92%~105%.
