掺锂和钠氯化钾色心晶体是一种较为有用的新型材料,它在研制和生产过程中需要进行成分分析,为此拟定了乙炔——空气火焰原子吸收光谱法。本文考察了影响锂和钠测定的因素,选择了最佳工作条件,诸如雾化气流量、测量高度、乙炔流量。灯电流和光谱通带宽度等,制定了测量较大的动态含量范围的分析方法。经两年多来实际应用证明方法简便、准确可靠,对研制工作起了一定的促进作用。
Lithium-doped and sodium-potassium chloride color-centered crystals are a new and useful type of material that requires compositional analysis during development and production. For this purpose, acetylene-air flame atomic absorption spectrometry was developed. This article examines the factors that affect the determination of lithium and sodium and chooses the best working conditions, such as atomizing gas flow, measuring height, acetylene flow. Lamp current and spectral passband width, etc., to develop a large dynamic range of measurement methods of analysis. After more than two years, the practical application proves that the method is simple, accurate and reliable and plays a certain role in promoting the research and development.
