Abstract: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.
Keywords:Low temperature atomic fluorescence spectrometry    Mechanism study    Arsenic
