铟氢化物发生原子吸收方法研究

Determination of Indium by Hydride Generation and Atomic Absorption Spectrometry

本文对铟氢化物发生方法进行了探讨,所采用的方法使铟氢化物的发生效率明显提高。在电加热石英管原子化器中得到的测定灵敏度为0.007μg(1％吸收),比文献报道值提高了一个数量级。并讨论了铟氢化物的发生机理与原子化机理。

A method of indium hydride generation is modified and the results show that the efficiency of generation is increased significantly. The sensitivity of determination in the electrically heated quartz tube atomizer is 0. 007 μg/0. 0044 which is one order of magnitude better than that reported earlier. The mechanisms of generation and atomization in the quartz tube are discussed.
