本文研究了在空气-乙炔火焰中不同价态和状态的砷对钙原子吸收信号的干扰,说明砷的干扰作用主要决定于砷的价态,不同价态砷的干扰程度和干扰规律存在极大差异。因此在处理干扰问题时,必须注意到元素不同价态对测定的影响。
In this paper, the interference of arsenic ions with different valences and states on the absorption of calcium atoms in air-acetylene flames was studied. The results show that the arsenic interference mainly depends on the valence state of arsenic. The interference degree and interference law of different valence states are extremely large difference. Therefore, in dealing with the interference problem, we must pay attention to the influence of different valence states on the determination.
