摘要
原子光谱分析法凭借高灵敏度与多元素检测潜力,成为汞痕量检测的重要手段。本文系统对比原子吸收光谱、原子荧光光谱及原子发射光谱的原理、设备及标准化应用,总结三者检测汞的优劣势与适用场景,并针对光谱、化学、物理及电离干扰提出消除策略,如氢化物发生、动态反应池及AI参数优化技术。研究表明,技术联用(ICP-AES与固相萃取结合)、智能化(微型测汞仪)与材料创新(量子点探针)是未来提升检测精度与效率的关键方向,为汞污染防控及标准制定提供了理论支持。
Atomic spectrometry,with its high sensitivity and potential for multi-element detection,has become a crucial method for trace mercury detection.This paper systematically compares the principles,instrumentation,and standardized applications of atomic absorption spectrometry,atomic fluorescence spectrometry,and atomic emission spectrometry.It also summarizes the advantages and disadvantages of each technique in mercury detection,as well as their respective application scenarios.Additionally,the paper proposes strategies for eliminating interferences,such as those from spectra,chemistry,physics,and ionization,through methods like hydride generation,dynamic reaction cells,and AI-based parameter optimization.The study concludes that the future development of mercury detection will focus on the integration of multiple technologies(ICP-AES with solid-phase extraction),miniaturization and intelligent design(micromercury analyzers),and material innovation(quantum dot probes).These advancements are expected to significantly enhance detection accuracy and efficiency.This paper also reviews the relevant national standards to provide theoretical support for mercury pollution control and standard formulation.
