摘要
用ＩＣＰ－ＡＥＳ法同时测定龙珠茶中１１种元素（Ｋ，Ｃａ，Ｐ，Ｍｇ，Ｍｎ，Ｆｅ，Ｚｎ，Ｃｕ，Ｃｏ，Ｎｉ，Ｃｒ）．对分析线的选择、酸效应和基体干扰等进行实验研究．方法简便可靠，回收率９４％～１０５％；相对标准偏差小于５％．
A method has been discribed for simultaneous determination of 11 elements (K,Ca,P,Mg,Mn, Fe,Zn, Cu, Co, Ni, Cr )in dragon-pearl tea by ICP-AES. Selection of analytical line,acidity effects and interferences of matrix elements have been studied. The method has been simple and of high accuracy. The recovery was 94% - 105 %,the RSD was less than 5 %.
