  • 专业解析

    发射光谱法(Emission Spectrometry) 是一种基于物质原子或离子受激发后释放的特征电磁辐射进行定性和定量分析的分析技术。其核心原理是:当样品中的原子或离子吸收能量(如热能、电能或光能)跃迁至激发态,随后返回基态或较低能级时,会释放出特定波长的光。通过检测和分析这些特征谱线的波长与强度,即可确定样品中的元素组成及其浓度。

    核心原理与过程

    1. 激发过程

      样品在激发源(如电弧、火花离子体或激光)作用下,原子外层电子吸收能量跃迁至高能态。例如电感耦合等离子体(ICP)通过高频电磁场使氩气电离形成高温等离子体(可达6000–10000 K),高效解离并激发样品组分 。

    2. 发射过程

      激发态电子不稳定,在返回低能态时释放光子,其波长($ lambda $)与能级差($ Delta E $)满足公式:

      $$ Delta E = E_2 - E_1 = frac{hc}{lambda} $$

      其中 ( h ) 为普朗克常数,( c ) 为光速。每种元素的原子结构独特,因此发射的谱线具有指纹特异性 。

    3. 分光与检测

      发射光经光栅或棱镜分光后形成光谱,由检测器(如光电倍增管、CCD)记录。通过对比标准谱线库(如NIST原子光谱数据库),可识别元素种类;谱线强度则与元素浓度成正比,实现定量分析 。
