氢化物–原子荧光光谱法测定灯盏细辛注射液中砷、汞的残留量

Determination of residual arsenic and mercury in Dengzhanxixin Injection by hydride generation atomic fluorescence spectrometry

目的建立测定灯盏细辛注射液中砷(As)、汞(Hg)限量的检测方法。方法采用氢化物–原子荧光光谱法测定As、Hg含量。结果在所选定的测定条件下,As、Hg的回收率分别为97.1%、90.2%(n=6)。结论此方法操作简便、快速,可用于灯盏细辛注射液中As、Hg残留量的测定。

To establish the methods for the content determination of arsenic （As） and mercury （Hg） in Dengzhanxixin Injection. Methods The As and Hg were measured by hydride generation-atomic fluorescence spectrometry （HG-AFS）. Results Under all the selected determination conditions, the recovery rates of As and Hg were 97.1% and 90.2%, respectively （n=6）. Conclusion The methods are simple and rapid to operate and can be used for the determination of residual As and Hg in Dengzhanxixin Injection.
