| Abstract: | As and Hg in Herba hedyotidis diffusae were digested by microwave method and determined by atomic fluorescence spectroscopy (AFS). The contents of As, Hg in Herba hedyotidis diffusae from 3 different regions were determined with RSD<3.0%. The sample recovery is within the range of 95.0%-103.0%. The method is simple and accurate;therefore it can be used in determining the contents of heavy metals in Chinese herbs. |
