ICP-AES法测定刺槐花中铁锰锌铜方法研究

Determination of Iron, Manganese, Zinc and Copper in Pagoda Flowers by ICP-AES

使用ＰＴＦＥ高压密封消化罐，用ＩＣＰ－ＡＥＳ法同时测定刺槐花中Ｆｅ、Ｍｎ、Ｃｕ、Ｚｎ元素，回收率均在９６～１０６％之间，相对标准差在７.９％以下，取得了满意的效果，

With PTFE autoclave, the method of the meantime determination of iron, manganese zinc and copper in pagoda flowers by ICP-AES has been studied. The rate of the recovery of the four element is from 96% to 106% and the relative standard deviation is under 7.9%. The results are satisfactory.
