ICP-AES与ICP-MS在水中测定金属元素的方法比较

摘要

水是膳食的一个重要组成部分，是一切生命必需的物质，在生命活动中发挥着重要功能。电感耦合等离子体光谱法（ICP-AES）以及电感耦合等离子体质谱法（ICP-MS）由于其适用于多元素分析及痕量元素分析等特点，在水中的重金属测定中有着广泛的应用。本文对两种方法的测定进行介绍并对其原理和特点进行比较。%Water is an important part of diet,it is a substance necessary for all life.In life activities it plays an important role. Inductively coupled plasma atomic emission spectrometry(ICP-AES)and inductively coupled plasma mass spectrom⁃etry(ICP-MS)because of their suitables for multi elemental analysis and trace element analysis,they are widely used in the determination of heavy metals in water. In this paper,the determination of two kinds of the methods will be introduced and contrasted.
