| Abstract: | Objective:To develop a inductively coupled plasma mass spectrometry(ICP-MS)method to determine seven heavy metal elements such as Pb,Cd,,Cr,As,Se,Ni,Cu in Liao Schisandra chinensis,Ginseng,Gentiana scabra,Liao Asa?rum,bupleurum.Method:The samples were dissolved by microwave digestion,Germanium(72Ge),indium(115In)and bismuth(209Bi)were used as internal standards.The contents of the above seven elements were determined by ICP-MS.Results:For all of the analyzed heavy metals,the correlative coefficient of the calibration curves was in the range of 0.9995~0.9999.The recovery rates were in the range of 85.7%~96.2%,and RSD were in the range of 1.9%~6.5%.Conclusion:The method is simple,rapid,accurate and can be used for the determination of these seven heavy metals in Chinese herbal medicines. |
