Abstract：In this article, through the condition experiment of simultaneous determination of rare earth and trace elements in wolfsbane by inductively coupled plasma mass spectrometry(ICP-MS)，the methods of low temperature ashing and nitric acid-overoxidation hydrogen(HNO3-H2O2) were compared. It was proved that the sample disposed with low temperature ashing for microelements and the sample disposed with acid digestion for rare earth satisfied the request for the method of determination. The accuracy is between 1.21% and 15.15%, and the precision is between 0.38% and 8.54%. The data of the experiment proved that the method completely satisfied the request for the determination of rare earth and microelements in the sample of Chinese herbal medicine.
Key words：Wolfsbane;Rare earth and trace elements;Inductively coupled plasma mass spectrometry
