原子荧光光度法是在原子吸收光谱法之后发展起来的一种新的痕量分析方法。用原子荧光光度法测定合金中某些元素已有报导;其中大部分采用色散系统装置,用氢—氩—空气火焰或空气-乙炔火焰及无电极或氙弧灯作光源。为了使仪器结构简单,造价低廉,我们曾研究了双道非色散原子荧光光度计,并分析了铝合金中锌、镁和锰。本文在过去工作的基础上,进一步将原子荧光光度法推广并应用于一般金属分析,并证实了原子荧光光度法在例行分析工作中可作为一种快速、简便、灵敏度高而又十分准确的分析方法。
Atomic fluorescence spectrometry is a new method of trace analysis developed after atomic absorption spectrometry. Some elements in alloys have been reported using atomic fluorescence spectrometry; most of them use dispersive system devices with hydrogen-argon-air or air-acetylene flame and electrodeless or xenon arc lamps as light sources. In order to make the instrument structure simple and cheap, we have studied two-channel non-dispersive atomic fluorescence photometer, and analyzed the aluminum alloy of zinc, magnesium and manganese. Based on the work in the past, this paper further generalizes the atomic fluorescence spectrometry and applies it to the general metal analysis, and proves that the atomic fluorescence spectrometry can be used as a fast, simple, sensitive and accurate method in routine analysis Analytical method.
