砷的原子吸收光谱法及荧光光谱法研究进展

Advances in Atomic Absorption Spectrometry and Fluorescence Spectrometry of Arsenic

本文探讨了样品中砷的各种检测方法,主要包括原子吸收光谱法(流动注射氢化物原子吸收法,石墨炉原子吸收法和火焰原子吸收光谱法)及荧光光谱法(氢化物原子荧光光谱法、X-射线荧光光谱法、电感耦合等离子体原子发射光谱法和电感耦合等离子体质谱法),并对不同检测方法进行检测限、精密度、重现性等指标的比较,总结出各自的优、缺点。砷的测定方法由过去的定性分析发展到精确的定量检测,准确定量测定砷的含量对食品、临床、药理、环境、生态等领域具有重要的意义。

This paper discusses the various arsenic detection.Through literature search,summarized,analysis and so on,and comparison different methods between detection limits,precision,reproducibility and other indicators,Summed up their respective advantages and disadvantages.Determination of arsenic from the previous qualitative analysis of the development to the accuracy of quantitative analysis,accurate quantitative detection of arsenic is important to food,clinical,pharmacological,environmental,and ecological and other fields.
