前言近廿年来原子吸收光谱分析技术的发展很快,并正在逐步地取代一些化学分析而成为微量、痕量金属元素分析和常规仪器分析的工具。原子吸收光谱分析技术近几年来的发展特点,一方面是无火焰原子化技术的迅速发展,因而大大地提高了分析灵敏度;伹如何提高石墨炉的温度和延长其寿命,改善分析精度,降低背景,提高信噪比和分析速度还是正在研究的课题。另一方面是其他学科新的技术和概念的引入和分析仪器的互相渗透正在导致原子吸收光谱分析技术的新发展。如激光技术正在用于研究固体试样的原子化和用可调谐激光器代替元素空心阴极灯
Introduction AAS has developed rapidly in the last 20 years and is gradually replacing some chemical analyzes as a tool for trace, trace elemental analysis and routine instrumental analysis. The development of atomic absorption spectroscopy in recent years has been characterized by the rapid development of flameless atomization on the one hand and greatly enhanced analytical sensitivity. 伹 How to increase the temperature and extend the life of graphite furnace to improve the analysis accuracy and reduce the background , To improve the signal to noise ratio and analysis speed is still the subject of research. On the other hand, the introduction of new technologies and concepts in other disciplines and the mutual penetration of analytical instruments are leading to new developments in atomic absorption spectroscopy. Such as laser technology is being used to study the atomization of solid samples and use tunable lasers instead of element hollow cathode lamp
