前言早在上一个世纪已经发现太阳光谱中有暗线光谱,试验证明这是高温下原子吸收的结果,并且吸收波长正是同种元素的发射波长。然而原子吸收光谱在分析上得到较大应用却迟到1955年 A.Walsh[1] 发表了一篇著名的论文《原子吸收光谱在分析上的应用》之后。经过以后几年的实践和研究,逐渐发现和解决了一些应用中的问题,原子吸收分光光度计的性能 Foreword Already in the last century has been found in the dark spectrum of solar spectrum, the experiment proved that this is the result of atomic absorption at high temperature, and the absorption wavelength is exactly the emission wavelength of the same species. However, atomic absorption spectroscopy has been greatly applied in the analysis was late 1955 A. Walsh [1] published a famous paper “Atomic Absorption Spectroscopy in the application of” after. After several years of practice and research, and gradually found and solved some of the problems in the application of atomic absorption spectrophotometer performance
