摘要
采用微波消解和ICP-OES对茶叶中10种微量元素进行了分析测定。拟定了测定方法,加标回收率在95.4%～102.4%之间,相对标准偏差(n=6)在0.75%～3.89%之间,满足分析要求。为茶叶中微量元素的检测分析提供了快速准确的测定方法。
10 trace elements in tea were simultaneously determined by microwave digestion and ICP-OES.The method was planned,the standardized recovery rate ranged from 95.4% to 102.4%,the relative standard deviation（n = 6） was 0.75%-3.89%,which met the requirement of analysis.The method can be used for the quick and accurate determination of trace elements in tea.
