前言铍的化合物有毒性,在环境分析中需要快速简便而又灵敏的测定方法,荧光分光光度法和气体色谱法虽灵敏,但需要较长时间的化学预处理,不符合简便,快速的要求。近年来无火焰原子吸收法已用于矿石,大气微粒,水、煤以及果树叶中铍的测定。由于共存元素的干扰,直接固体取样法仅适用于煤及果树叶等有机体中铍的测定。在含有大
Introduction Beryllium compounds are toxic and require rapid, easy and sensitive assays for environmental analysis. Fluorescence spectrophotometry and gas chromatography, although sensitive, require longer chemical pretreatments and do not meet the simple and fast requirements. In recent years, flameless atomic absorption spectrometry has been used for the determination of beryllium in ores, atmospheric particulates, water, coal and fruit leaves. Due to the interference of coexisting elements, the direct solid sampling method is only suitable for the determination of beryllium in organic matter such as coal and fruit leaves. Contains large
