Determination of several trace elements in tea by microwave digestion and ICP-OES

Yang Yun-jing

Abstract

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.
