| 摘 要： | 研究了巯基棉分离富集、单缝石英管FAAS法测定铋的最佳条件。以盐酸作介质，巯基棉富集铋的最佳吸附酸度为0．1－0．2mol/L(盐酸），定量洗脱酸度为2mol/L(盐酸）。该法用于测定水中痕量的铋，回收率为96％－102％，相对标准偏差为4．8％。

| Abstract: | The optimum condition for determination of the trace bismuth in the river water by FAAS with slotted quartz tube after separation and enrichment with sulhydryl cotton is studied. The bismuth is enriched when the concentration of hydrochloric acid is from 0.1 - 0.2 mol/L and eluted quantitatively with 2 mol/L hydrochloric acid. This method is used to determine the trace bismuth in water with the recovery of bismuth being 96% - 102% ,and the relative standard deviation is 4.8% . |
