| 摘 要： | 目的考察自然铜炮制前后微量元素的含量变化，以探讨自然铜炮制机理。方法用电感耦合等离子体发射光谱法（ICP）测定生、煅自然铜水煎液中镁、钙、铬、锰、铁、钴、镍、铜、锌、铅10种元素的含量并进行比较。结果自然铜炮制后铅元素的含量降低，其他9种被测元素的含量均有不同程度的增加。结论自然铜经煅淬后，10种相关元素的煎出量变化很大。

| Abstract: | Objective To investigate the changes of microelement in curde and calcined pyritum, and approach the process mechanism of pyritum. Methods The crude and calcined pyritum were extracted in water decocting. Subsequently, the content of ten elements was determined by inductively coupled plasma emission spectrometry （ICP） and compared. Results After being calcined, the content of Pb in pyritum decreased, while the content of the other nine elements investigated all increased in different degrees. Conclision After being calcined, the content of ten elements in pyritum changed largely. |
