[Objective] To develop a method for the determination of Selenium in Chinese medicinal herb Erigeron breviscapus (Vant.) Hand.-Mazz.. [Method] Various test conditions and effect factors for determination of Selenium by flow injection-hydride generation-atomic absorption spectrometry (FI-HG-AAS) were discussed. [Result] The linear range for Selenium is 0-100 μg/L. The relative standard deviation is less than 2% and the recovery is 98%-102%. [Conclusion] This method is simple, rapid and has been applied to the determination of Selenium in Chinese medicinal herb E.breviscapus with satisfactory results.
