引言铍是一种毒性较大的元素。极少量的铍及其化合物都可累积在人或其它动物的肺里导致铍中毒,因此,测定水中铍就显得十分重要。测定水中 ppb 级的铍量,近年来采用的测定技术主要的有化学法、气相色谱法、火焰原子吸收光谱法、石墨炉原子吸收光谱法和石墨炉原子发射光谱法。但是,上述方法有的是检测限还不够低,需要采用大量浓缩、富集或分离等过程;有的是因干扰严重,带来较大误差。本文采用电感耦合高频等离子焰炬(简称 ICP)新 Introduction Beryllium is a more toxic element. Very small amounts of beryllium and its compounds can accumulate in the lungs of humans or other animals causing beryllium poisoning, so it is important to measure beryllium in water. Determination of ppb grade water beryllium, in recent years the main measurement techniques used are chemical, gas chromatography, flame atomic absorption spectrometry, graphite furnace atomic absorption spectrometry and graphite furnace atomic emission spectrometry. However, some of the above methods have the limit of detection not low enough, which requires a large amount of enrichment, enrichment or separation processes; some are subject to serious interference and large errors. In this paper, inductively coupled plasma torch (referred to as ICP) new
