摘　　要：本文详细研究了铋化氢与汞离子反应条件，建立了一个氢化物发生－冷原子荧光法间接测定痕量铋的新方法。此法用于测定水及铜合金中的痕量铋，简便、快速、灵敏度高、重现性好，水中铋的检测限为０．５ｎｇ／ｍＬ，回收率为９５％～１０５％。A new method is described for the indirect determination of trace amounts of bismuth using hydride generation-cold atomic fluorescence techniques.The experimental conditions for the reaction of bismuth hydride with mercury have been carefully studied.This method has high sensitivity and good reproducibility.It has been applied successfully to the determination of trace amounts of bismuth in water and alloys.The detection limit is 0.5ng/mL in water samples and the recovery is 95%～105%.
