摘要
使用AFS-820双道原子荧光光度计,运用氢化物发生——原子荧光光谱法同时测定了腾冲火山区的大滚锅、叠水河两温泉各水样中的微量元素As、Sb,研究探讨了同时测定两种元素过程中的仪器最佳条件设置。在21天的连续采样检测中,每天绘制标准曲线相关系数RAs≥0.999 6,RSb≥0.999 5,检测结果为:大滚锅水样As含量较高,均值为867.50μg/L,Sb含量均值为30.06μg/L,叠水河水样检出含有微量As,未检出含有Sb。
Using the double-channel-atomic-fluorescence spectrophotometer, AFS -820, we simultaneously determine the contents of trace element of Arsenic and Antimony by Hydride Generation--Atomic Fluorescence Spectrome- try of water samples in hot spring of Dagunguo and Dieshuihe in Tengchong volcanic area. And we determine the optimum condition of instrument for the simultaneous determination of two elements. In the 21-days' continual sampling and detecting, the correlation coefficient of the standard curve RAs is above 0. 999 6 and Rsb is above 0. 999 5 every day. The results show that the content of As is higher in the Dagunguo spot, and the average value of As is 867.50 μg/L and that of Sb is 30. 06 μg/L. The content of Dieshuihe spot contains minimal As, and Sb is not detected.
