微波消解-ICP-AES法测定中药材乳香中的微量元素

Determination of Microelement in Chinese Traditional Medicine Frankincense by Microwave Digestion and ICP-AES

用电感耦合等离子体发射光谱法(ICP-AES)测定中药材乳香中的微量元素。首先用微波溶样技术,以浓HNO_(3)作为消解剂对乳香样品进行预处理,然后测定了Al、As、Ba、Cd、K、Li、Mn、Ni、Pb、Se、Sr、Tl、Zn等13种微量元素的含量。元素加标回收率实验数据为94.0%~107.5%,分析数据可靠性高。该方法可用于树脂类中药材中微量元素的快速检测。

Front uses the concentrated HNO_(3) achievement to dispel the medicinal preparation to dispel through the microwave to the sample carries on processes,using inductive coupling ICP-AES immediate determinant frankincense in Al,As,Ba,Cd,K,Li,Mn,Ni,Pb,Se,Sr,Tl and Zn so on 13 kind of elements content.Through increase standard recycling experiment,each analysis element Canadian sign returns-ratio between 94.0%~107.5%.The method is rapid and convenient,with high accuracy and has been applied to the determination of resin traditional Chinese Medicine samples with satisfactory results.
