[Mechanism of arsenic hydride generation and atomization in low temperature atomic fluorescence spectrometry].
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 H2 simultaneously, the mechanism of AsH3 generation was studied. Experimental results show that the atomization process of AsH3 might be carried out mainly by collision with hydrogen radical.
