原子发射光谱法(Atomic Emission Spectrometry, AES)是一种通过检测气态原子或离子受激发后产生的特征辐射,从而确定物质元素组成及含量的分析技术。其核心原理基于原子能级跃迁:当样品中的原子被外部能量(如电弧、火花或等离子体)激发至高能态后,电子返回基态时会释放特定波长的光,这些光的波长和强度与元素种类及浓度直接相关。
该方法主要由三部分构成:
在应用领域上,原子发射光谱法被广泛用于环境监测(如重金属污染检测)、冶金工业(金属纯度分析)和地质研究(岩石矿物成分鉴定)。其优势包括多元素同时检测能力(单次实验可分析70余种元素)以及较低的检测限(部分元素可达ppb级)。
目前,电感耦合等离子体原子发射光谱(ICP-AES)已成为该技术的标准方法,相关操作规范可参考国家标准《GB/T 23942-2022 化学分析实验室能力验证技术要求》。

Atomic Emission Spectrometry (AES) 是一种用于分析物质元素组成和含量的光谱技术,其核心原理是通过测量气态原子或离子受激发后发射的特征光谱来实现分析。以下是详细解释:
当原子被热能或电能激发时,外层电子跃迁到高能级,随后返回低能级时会释放能量,表现为特定波长的光。这些光的波长与元素种类相关,强度则与元素浓度成正比。通过分光系统检测这些光谱,可确定元素的种类和含量。
AES是Atomic Emission Spectrometry的常用缩写,需注意与Atomic Absorption Spectrometry(AAS,原子吸收光谱法)区分。AAS基于原子对光的吸收,而AES基于光的发射。
