近年来,氢化物发生原子吸收法已向自动化、小体积的方向发展,如结合使用流动注射技术和富集方法,使灵敏度和检出限都有所提高。一些工作者还在原子化反应机理上也做了很多研究和探讨。本文是在原工作的基础上做了一些改进。仍采用自制发生器,手动注射,但加入一简易储气装置和电磁搅拌,并在氮气中 In recent years, hydride generation atomic absorption spectrometry has been automated, small volume direction, such as the combination of flow injection and enrichment methods, the sensitivity and detection limits have increased. Some workers also do a lot of research and discussion on the atomization reaction mechanism. This article is based on the original work done some improvements. Still using a homemade generator, manual injection, but adding a simple gas storage device and electromagnetic stirring, and in nitrogen
