| Abstract: | OBJECTIVE To determine the contents of the six harmful elements:lea d,chromium,mercury,arsenic,copper and cadmium,in Chinese herbal medicine.METHODS Samples were pretreated by microwave-assisted digestio n technology and then the contents of the six elements were determined by inductively coupled pla sma mass spectrometry(ICP-MS)simultaneously.RESULTS The avera ge contents of the 6 elements from 15 batches accord with Cu>As>Pd>Hg>Cr>Cd.CONCLUSION Microwave-assisted digestion-ICP-MS method can determine the contents of 6harmful elements in the Chinese herbal medicine simultaneously.Efficient,fast,stable and accurate,this method is relatively instructive to the quality cont rol of the traditional Chinese medicine. |
