原子荧光光谱法(AFS)是原子光谱法中的一个重要分支。是介于原子发射光谱(AES)和原子吸收光谱(AAS)之间的光谱分析技术。至今已经走过50多年的发展道路。因其具有两种技术的优点,同时又克服了两者的不足,得到专家学者的广泛关注和深入研究。尤其是氢化物发生(HG)与原子荧光(AFS)的联用技术研究,为AFS在我国的普及和推广打下了基础。本文简单介绍了AFS的基础及氢化物发生-原子荧光法(HG-AFS)分析原理、分析特点及缺陷。重点综述了近年来HG-AFS分析技术在环境卫生领域的空气样品检测和水质检测中的应用进展,利用其分析特点对一些痕量元素(砷、硒、锡、锑、汞、铅等)检测的应用。阐述了AFS在环境卫生领域中发挥的重要作用及其广阔前景。
Atomic fluorescence spectroscopy (AFS) is an important branch of atomic spectroscopy. Is between the atomic emission spectroscopy (AES) and atomic absorption spectrometry (AAS) between the spectral analysis technology. So far it has gone through more than 50 years of development. Because of its advantages of two technologies, but also overcome the shortcomings of the two, experts and scholars have been widely concerned and in-depth study. In particular, the study on the combination of hydride generation (HG) and atomic fluorescence (AFS) has laid the foundation for the popularization and promotion of AFS in our country. This paper briefly introduces the basis of AFS and the principle of hydride generation-atomic fluorescence spectrometry (HG-AFS), and analyzes its characteristics and defects. In this paper, the progress of HG-AFS analysis technology in air samples and water quality testing in the field of environmental health is reviewed in detail. The characteristics of some trace elements (arsenic, selenium, tin, antimony, mercury and lead) Applications. It expounds the important role and broad prospects of AFS in the field of environmental health.
