用原子吸收光谱法测定砷有多种方法,各有其特点。本文将介绍采用塞曼背景校正技术和基体改进剂减轻或消除基体干扰,以标准加入法测定海水中痕量砷。方法灵敏度
There are many ways to determine arsenic by atomic absorption spectrometry, each with its own characteristics. This article describes the use of Zeeman background correction techniques and matrix modifiers to mitigate or eliminate matrix interferences and standard addition method for the determination of trace amounts of arsenic in seawater. Method sensitivity
