Determination of Zinc in Rehmanniae Glutinosa by Suspension Sampling-flame Atomic Absorption Spectrometry

XU Wen-jing WANG Shi-lei SUN Yue-zhi (Jiaozuo Normal College,Henan,Jiaozuo 454001,China)  
[Objective] To determine the concentrations of zinc in rehmanniae glutinosa by flame atomic absorption spectrometry (FAAS).[Methods] Agar sol was used as a suspending agent.Crushed and sieved rehmanniae glutinosa sample was suspended homogeneously in the agar sol and introduced into air-acetylene flame,then zinc in the sample was determined directly.[Results] It has been ap,plied to the determination of zinc in rehmanniae glutinosa,and the determined results were consistent with those obtained by HNO_3+H_2SO_4+HCIO_4 method.[Conclusion] It is possible to determine the sample of rehmanniae glutinosa by suspension sample introuction method.This method is convenient,rapid and accurate.
