摘　　要：采用氢氧化铁共沉淀,分离卤水中大量盐类,盐酸溶解沉淀,氢化物-原子荧光光谱法测定卤水中痕量的As、Sb和Bi等。方法检出限LD(As)=0.02μg/L、LD(Sb)=0.01μg/L、LD(Bi)=0.01μg/L,RSD分别为0.99%、1.08%、0.69%(n=12),回收率分别为:92.0%—96.0%、88.0%—104%、94.0%—104%。实验结果表明,该方法检出限低、灵敏度高、测定结果准确可靠、操作简单快速,可完全满足卤水中痕量As、Sb、Bi的测定。The amounts of arsenic, antimony and bismuth in halo water was determined by hydride generation-atomic fluorescence spectrometry with co-precipitation of ferric hydroxide. Under the optimum condition, the detection limit of arsenic, antimony and bismuth are 0.02, 0.01 and 0.01μg/L, with the standard addition recovery of 92.0%-96.0% （arsenic）, 88.0%-104% （antimony） and 94.0%-104% （bismuth）, respectively. The method was applied to the analysis of arsenic, antimony and bismuth in halo water with satisfactory results.
