摘要
自1978年B.V. L′vov提出石墨炉内探针原子化技术以来,许多作者对该技术进行了研究,并将其应用于实际样品的测定,国内亦有人作过系统的评述,但对元素在石墨探针表面上的原子化机理却报道不多。本文应用X射线衍射分析与其它一些实验,观察和研究了镉和铝在石墨探针表面上原子化过程中的形态变化,阐明了镉和铝的原子化历程。
The atomization mechinism of cadmium and aluminium on the graphite probe surface in the graphite furnace is studied. The result shows that the atomization of cadmium and aluminium on the graphite probe surface originates from the thermolysis of their monooxides. The appearance temperature of Cd and Al is identical with the thermolysis temperature of their oxides respectively. The active energy of atomization is related to the bond energy of M-O of their oxide.
