摘要
目的:探索原子荧光分析技术在中药材砷、汞含量测定上的应用。方法:以湿法消解样品,原子荧光光谱法直接测定。结果:方法学考察得砷平均回收率为101.3%,RSD为0.30%(n=6),汞平均回收率为101.0,RSD为0.29%(n=6)。检出限DL(As)=0.029μg.L-1,DL(Hg)=0.0076μg.L-1。结论:该方法具有操作简单,灵敏度高,准确度好等优点,可广泛应用于砷和汞的测定。
Objective：Explore atomic fluorescence spectrometry and its application in determination of As and Hg in medicinal materials.Method：Determination of As and Hg in Chinese medicinal materials by atomic fluorescence spectrometry using wet digestion.Result：The relative standard deviation of As and Hg which were 0.30% and 0.29%.The recovery of the method 101.3% and 101.0%;The detection limit of As and Hg was 0.029 μg·L-1 and 0.0076 μg·L-1.Conclusion：The method has high sensitivity,precision and accuracy were both meet requirements,it is widely used in determining the contents of As,Hg.
