用原子荧光分光光度法测定了不同产地的冬虫草中汞含量,对各种测定影响因素作了一定的研究并予以择优。方法检出限为0.012μg/L,在对实样进行分析的基础上作了回收试验,得出结果为92%~96%。
The mercury content in Cordyceps militaris from different origins was determined by atomic fluorescence spectrophotometry. The factors that affect the determination of mercury were studied and selected. The detection limit of the method was 0.012μg/L. Based on the analysis of the actual sample, a recovery test was conducted and the result was 92%~96%.
