摘要: 氢化物原子吸收法已经得到广泛应用,但有关氢化物原子化机理一直存在争议,且多集中在AsH3和seH2方面,本文对GeH4在电热石英管中的行为进行了研究。

关键词: 氢化锗, 电热石英管, 原子吸收光谱

Abstract: In the electrically heated quartz tube, most of GeH4are directly atomized, i. e. , GeH4(g) →Ge(s). Only a few of GeH4are indirectly atomized, i. e. , GeH,i(g)→Ge(g)→Ge(s). When the temperature of the quartz tube is higher than960K, oxygen in the gas entering the quartz tube will interfere with atomization of GeH4, and the process of atomization is Ge(g) +(1/2)O2(g)→GeO(g).
