摘要：

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 AsH3 generation was studied. Experimental results show that the atomization process of AsH3 might be carried Out mainly by collision with hydrogen radical.
