| Abstract: | [Objective] The inductively coupled plasma mass spectrometry (ICP-MS) was constructed to determine the contents of lead, cadmium, mer-cury and arsenic in Archyranthes bidentata Blume. [Method] Under the optimum operation condition of ICP-MS, the samples were digested by microwave. The dement 114In was taken as an internal standard dement to compensate body effect and ICP-MS method was used to determine the contents of lead, cad-mium, mercury and arsenic. [Result] For the determined elements, the correlation coefficient (r) of standard curve, was over 0. 9995 and recovery rate was from 96.7% to 106.4% while RSD was less than 11.2%. The result of determination showed that the heavy metal content in Archyranthes bidentata Blume. beyond standard was serious. [Conclusion] The constrocted ICP-MS method with simple operation, rapid response, accuracy and high sensitivity in this experiment could be used for quality control of Chinese medicinal materials by detecting heavy metal contents in different Chinese medicinal materi-als from original places. |
