由于周期系中的 Ge、Sn、Ph、As、Sb、Bi、Se、Te 八个元素的氢化物,在常温下就可从酸性介质中逸出,并有较低的分解温度,很容易瞬间原子化,这就给原子吸收测定带来很大的方便。因此,国内外有关这方面的文献已有大量报道,普遍认为是提高测定灵敏度的一种好方法.氢化物发生器除自动、半自动的商品仪器外,手动氢化物发生装置的应用更广泛。这是因为此装置便于实验者根据需要自行设计制造,操作简便。其形式虽多种多样,但其原理、基本结构却大同小异。在前人工作的启发下,本文对上述装置进行了改进,得到一种结构简单、操作方便、重现性较好的氢化物发生装置。
Hydrogenates of eight elements of Ge, Sn, Ph, As, Sb, Bi, Se and Te in the periodic system can escape from the acidic medium at normal temperature and have a relatively low decomposition temperature, Atomization, which gives a great convenience for atomic absorption spectrometry. Therefore, there are a lot of reports about this field at home and abroad, and it is generally considered as a good method to increase the sensitivity of determination.Higher generator is more widely used than automatic and semi-automatic commercial instruments. This is because the device is easy for experimenters to design and manufacture according to their needs and is easy to operate. Although its form is varied, its principles and basic structure are much the same. Inspired by the predecessors’ work, this paper improves the above device and obtains a hydride generation device with simple structure, convenient operation and good reproducibility.
