大试管回流消解-等离子体发射光谱／质谱法测定植物样品中多元素

Determination of Major and Trace Elements in Plant Samples by Inductively Coupled Plasma-Atomic Emission Spectrometry/Mass Spectrometry with Sample Reflux Digestion

摘要: 采用大试管和红外加热的多孔控温消解炉的简单装置消解植物样品，电感耦合等离子体发射光谱／质谱法测定其中的主量和痕量元素，对消解温度、消解时间、消解溶剂、样品取样量等条件进行考察。用植物国家一级标准物质进行前处理及测定，验证方法的可行性，测定值与标准值基本吻合。方法不仅能同时测定B、Ba、Ca、Cd、Cu、K、Mg、Mn、Na、Ni、P、S、Zn、CoSr、Pb、Cr等元素，还适用于Hg、As挥发性元素的消解测定。方法的精密度（RSD，n=10）≤10％。

Abstract: Plant samples were digested with big reflux test tube and infrared heating furnace and the major and trace elements were determined by inductively coupled plasma-atomic emission spectrometry/mass spectrometry(ICPAES/MS).Some important analytical parameter
