摘　　要：目的:进行硫磺熏蒸前后白芍样品中有害重金属、硫及微量元素的分析。方法:采用湿法消解前处理,电感耦合等离子发射光谱(ICP-AES)法测定。结果:白芍经硫磺熏蒸后Cu,S元素含量增加,Zn元素含量降低,并且在硫磺熏蒸白芍样品中检测到了重金属As,Hg残留。结论:硫磺熏蒸可能会使白芍中残留有害重金属及大量对人体有危害的硫,同时改变部分微量元素的含量。Objective： To analyze the contents of harmful heavy metals,sulfur and trace elements from Paeoniae Radix Alba before and after sulfur-fumigated process.Method： Samples were pretreated by wet digestion and then subjected to elements analysis by inductively coupled plasma-atomic emission spectrometry（ICP-AES）.Result： The contents of Cu and S elements were increased,while the content of Zn element was decreased in Paeoniae Radix Alba after sulfur-fumigated process compared with the samples dried in the sun.Moreover,heavy metallic elements,such as As and Hg,were detected in Paeoniae Radix Alba after sulfur-fumigated process.Conclusion： Sulfur fumigated process may cause residual of heavy metals and sulfur which are harmful to human body and change the contents of some trace elements.
