原子吸收光谱分析法已愈来愈普及,虽然关于它对许多元素的分析灵敏度高及较小的干扰效应是众所周知的,但是仍有不少元素在火焰原子吸收法中(包括应用高温的化学火焰)其检测限并不理想,原子化的不完全是重要的原因之一,某些元素的化学干扰也不能忽略,理解有关干扰效应的机理对于分析者处理工作中的许多问题都是重要的依据,本文拟对与此有关的原子池中的吸收原子的数目、光谱干扰和电离干扰的概念作一些讨论。
Atomic absorption spectrometry has become more and more popular. Although it is well known that it has high analytical sensitivity for many elements and small perturbation effects, there are still many elements that are widely used in flame atomic absorption spectrometry (including the application of high temperature chemical flame ), The detection limit is not ideal. Incomplete atomization is one of the important reasons. The chemical interference of some elements can not be neglected. Understanding the mechanism of interference effect is an important basis for many problems in the processing of the analyst , This article intends to discuss the concept of the number of absorbed atoms, spectral interferences and ionization disturbances in the associated atomic pools.
