| Abstract: | A method for the determination of trace bismuth by on-line hydride generation atomic fluorescence spectrometry from alkaline solutions was established. The manifold and oper-ating program for on-line hydride generation are designed and the optimal conditions for hydride generation from alkaline solutions are investigated. This method is simple and rapid. The chemi-cal interferences of transition elements are prevented, and the proposed method has been applied to the determination of trace bismuth in copper samples with satisfactory. |
