ICP-AES法测定三种蒙药中多种元素含量

Determination of Multi-elements in Three Kinds of Mongolian Drug by ICP-AES

目的：测定额日敦-乌日勒、阿密别日各其-11及嘎日迪-13中钙、磷、铜、钾、铁、钠、锰、锌、镁、锡、硅、钛的含量；方法：采用湿法对三种具有镇静安神功效的蒙药进行消化，以电感耦合等离子体发射光谱仪（ICP-AES）检测样品中12种元素的含量；结果：三种蒙药中对人体有益的常量及微量元素含量丰富.所研究的元素的回收率在92.4%～106.3%之间.结论：湿法消解和 ICP - AES 相结合检测常微量元素具有省时、省力、环境污染小，测定结果快速、准确等优点.

Objective：Ca,P,Cu,K,Fe,Na,Mn,Zn,Mg,Sn,Si and Ti in Mongolian Drug Eridun-Wurile,Ami Bierigeqi-11 and Garidi-13 were determined. Methods：Wet digestion procedure was applied under optimized condi-tions for digesting Mongolian Drug,Element concentrations were determined by ICP-AES. Results：The result indi-cated that Mongolian Drug were abundant in constant and trace element contents in the human body,the average re-coveries for all elements were 92.4%to 106.3%under optimum experiment condition. Conclusion：Conbining the wet digestion technology with the ICP-AES,There were a lot of merits of time-saving,reduces effort,small environ-mental pollution,fast and accurate determination result in determining constant and trace elements.
