大黄中18种无机元素的含量测定

The contents determination of eighteen inorganic elements in Radix et Rhizoma Rhei

目的:建立大黄中无机元素含量的测定方法。方法:采用原子荧光、电感耦合等离子光谱、电感耦合等离子质谱等方法来进行无机元素的测定。结果:测定了大黄中Ca、Cu、Fe、Mg、Zn、Sr、V、Cd、Cr、Co、Al、Mn、Mo、Ni、P、Pb、As、Se等18种无机元素的含量。结论:分析方法简便、快捷、准确,适于无机元素的分析测定。

Objectlve：To establish the methods for the determination of the inorganic elements in Radix et Rhizoma//hei. Methods： The AFS,ICP-AES and ICP-MS were adopted to determine the contents of inorganic elements. Results：It was determined that the eighteen inorganic elements such as Ca,Cu,Fe,Mg,Zn,Sr,V,Cd,Cr, Co,AI,Mn,Mo,Ni,P,Pb,As,Se and so on. Conclusion：The methods are simple, rapid, accurate, which are appropriate to determine the contents of inorganic elements.
