【摘要】 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。更多还原

【Abstract】 The effect of different valences and states of arsenic on calcium has been studied in an air-acetylene flame. The results show that the interference is determined primarily by the valences of arsenic. The level and regulation of interference of As(V) and As(Ⅲ) are very different. in investigation of their interferences, it is necessary to notice their different valences and states.更多还原
