Abstract:
Objective:To determine the contents of 5 heavy mental elements , Cr, Pb, Cd, Cu and Zn, in vacant gelatin capsule shells.Methods:Graphite furnace atomic absorption spectrometry was used to determine Cr , Pb and Cd, and flame atomic absorption spectrometry was used to determine Cu and Zn .Results: The vacant gelatin capsule shells contained Cr , Pb, Cd, Cu and Zn up to 1.850, 0.404, 0.019, 6.295,5.839 mg· kg-1, respectively.Conclusion:The method can be used for the content determination of Cr, Pb, Cd, Cu and Zn in vacant gelatin capsule shells , which provides scientific basis for the development of quality standard .
