基于微波消解的ICP-OES/ICP-MS法测定茶叶中30种矿物质元素
Determination of 30 mineral elements in tea by microwave digestion coupled with ICP-OES/ICP-MS
摘要
Abstract
In this paper,the determination mineral elements in tea were analyzed by utilizing microwave digestion-ICP-OES/ICP-MS method.ICP-OES was used to determine the contents of nutrition elements with the detection limits no larger than 0.05 mg/L and correlation coefficients of 0.9995 ～ 1.0000.The heavy metals and total content of rare earth elements were determined by ICP-MS,combining with the detection limit of no larger than 0.082 μg/L and correlation coefficients of 0.9996 ～1.0000.This simple,fast and accurate method was applied to the analysis of mineral element compositions of 32 tea samples.This work could provide data reference for the scientific evaluation of mineral elements content in tea.关键词
