摘　　要：目的研究了AFS-2202a型双道原子荧光光度计测定道地黄芪中Se的方法和含量。方法AFS-2202a型双道原子荧光光度计测定法。结果Se的线性回归方程:Y=65.7777X-49.1234;相关系数:R=0.9996;线性范围:3.125～50μg/L;回收率为91.2%～103.8%;检出限为0.036μg/L;道地黄芪中Se的含量大约为0.033μg/g。结论原子荧光法测定道地黄芪中Se的方法操作简单、快速节省试剂,适合广泛推广。Objective To study the method of determination and content of selenium （Se） in genu- ine astragalus with AFS - 2202a dual - channel atomic fluorescence spectrophotometer. Methods AFS - 2202a atom fluorescence spectrometer was applied to the determination. Results Regression equation of the linear of Se ： Y = 65. 777 7X - 49. 123 4 ; Correlation coefficient ： R = 0.999 6 ; the linear ranger： 3. 125 - 50 μg/L;the recovery rate： 91.2% - 103.8% ;the detection limit： 0.036 μg/L. The content of Se in genuine astragulus ： about 0.033 μg/L. Conclusion Atomic fluorescence spectrophotometer is operated in the determination of Se easily and rapidly,which saves reagents and is suitable to be promoted extensively.
