ICP—AES测定昆仑雪菊中的6种微量元素

Determination of Six Kinds of Trace Elementsin in Kunlun Snow Chrysanthemum by ICP-AES

应用ICP—AES同时测定昆仑雪菊样品中的6种微量元素（Sr、Fe、Mn、Zn、Cu、Ba）含量。检测结果精密度与准确度良好，加标回收率在95．0％-104％之间，相对标准偏差均在5％以内。方法简便、快速、可靠、结果令人满意。

Six kinds trace elements （Sr, Fe,Mn, Zn,Cu, Ba） in the samples of Kunlun snow chrysanthemum were determined Simultaneously by ICP-AES. The precision and accuracy of detection results were good;and the recoveries were in the range of 95.0% -104% with RSD less than 5%.The method is simple, quickly and the results were satisfied.
