低温氢化物原子荧光法砷的氢化反应和原子化

Mechanism of Arsenic Hydride Generation and Atomization in Low Temperature Atomic Fluorescence Spectrometry

以空心阴极灯作激发光源，选择了低温氢化物原子荧光法测定砷的最佳工作参数。采用双氢化发生法，研究了砷的氢化反应机理和原子化机理。

With a hollow cathode lamp as exciting source,the optimum working parameters for the determination of As were selected.By adopting two hydride generators to generate hydride and H 2 simultaneously,the mechanism of AsH 3 generation was studied.Experimental results show that the atomization process of AsH 3 might be carried out mainly by collision with hydrogen radical.
