The Best Condition for Determining As, Sb and Bi by on-line Double Capillary Hydride Generation-Atomic Absorption Spectrometry

By on-line double capillary atomic absorption spectrometry with hydride generation is a new sensitive and precise method. The conditions for determine As, Sb and Bi by on-line double capillary hydride generation\|atomic absorption spectrometry are investigated with orthogonal experiment design. The best measuring condition was determined by this way. The good results are oltained during the determination of samples, RSD3.26%.
