摘　　要：建立了碱性模式氢化物发生-原子荧光光谱法测定多金属矿石中微量铋的分析方法，对仪器和实验条件进行了最佳化选择，讨论了共存离子的影响。方法经国家标准物质分析，测定值与标准值吻合，方法精密度（RSD，n=12）为2．97％，回收率为95％～104％。A method for the determination of micro-amount of bismuth in polymetallic ores by hydride generation-atomic fluorescence spectrometry with alkaline mode was developed. The instrumental parameters were optimized and the effect of coexisting ions on the determination was studied. The method was validated by determination of micro-amount of Bi in National Standard Reference Materials and the results were in agreement with certified values. The recovery of the method was 95% - 104% with precision of 2.97% RSD（ n = 12）.
