一、绪言原子荧光光谱法是一种新的痕量分析方法,它与原子吸收光谱法和火焰发射光谱法有许多共同之处。这种新方法的灵敏度高,可采用无色散的简单仪器系统,能同时多元素测定,还可进行无火焰分析。原子蒸气的荧光早在十九世纪末期和二十世纪初期就由许多物理学家作过研究。1956年Boers等就钠的共振荧光研究其基本物理和化学过程取得了较大的进展。在1962年国际光谱学讨论会上,Alkemadet概要地介绍了在火焰中激发原子的方法,测量不同火焰中钠D双线共振萤光的量子效率的装置,并且提出了原子荧光可以在分析化学中得到应用。但是这种方法在分析化学中的应用还是在1964年以后 I. INTRODUCTION Atomic fluorescence spectrometry is a new method of trace analysis that has much in common with both atomic absorption spectrometry and flame atomic emission spectrometry. The new method is highly sensitive and allows the use of a simple instrument system without dispersion, simultaneous multi-element determination and flameless analysis. The fluorescence of atomic vapors was studied by many physicists as early as the late nineteenth and early twentieth centuries. In 1956, Boers et al. Made great progress in the fundamental physical and chemical processes of sodium resonance fluorescence study. At the 1962 International Symposium on Spectroscopy, Alkemadet provided an overview of the method of exciting atoms in a flame, a device for measuring the quantum efficiency of sodium D two-line resonance fluorescence in different flames, and proposed that atomic fluorescence can be used in analytical chemistry Get applied. However, this method is still used in analytical chemistry after 1964
