| Abstract: | The working conditions of determination of trace elements by flame atomic absorption spectrometry were decided,then the equations of linear regression were established in this paper.The determination of trace elements in natural Poria Cocos and liquid fermented poria cocos were done by flame atomic absorption spectrometry.The results showed that they had some differences in trace elements concentration.At the same time,the reasons which caused differences were explained. |
