原子發射光譜法(Atomic Emission Spectrometry, AES)是一種通過檢測氣态原子或離子受激發後産生的特征輻射,從而确定物質元素組成及含量的分析技術。其核心原理基于原子能級躍遷:當樣品中的原子被外部能量(如電弧、火花或等離子體)激發至高能态後,電子返回基态時會釋放特定波長的光,這些光的波長和強度與元素種類及濃度直接相關。
該方法主要由三部分構成:
在應用領域上,原子發射光譜法被廣泛用于環境監測(如重金屬污染檢測)、冶金工業(金屬純度分析)和地質研究(岩石礦物成分鑒定)。其優勢包括多元素同時檢測能力(單次實驗可分析70餘種元素)以及較低的檢測限(部分元素可達ppb級)。
目前,電感耦合等離子體原子發射光譜(ICP-AES)已成為該技術的标準方法,相關操作規範可參考國家标準《GB/T 23942-2022 化學分析實驗室能力驗證技術要求》。
參考來源:
Atomic Emission Spectrometry (AES) 是一種用于分析物質元素組成和含量的光譜技術,其核心原理是通過測量氣态原子或離子受激發後發射的特征光譜來實現分析。以下是詳細解釋:
當原子被熱能或電能激發時,外層電子躍遷到高能級,隨後返回低能級時會釋放能量,表現為特定波長的光。這些光的波長與元素種類相關,強度則與元素濃度成正比。通過分光系統檢測這些光譜,可确定元素的種類和含量。
AES是Atomic Emission Spectrometry的常用縮寫,需注意與Atomic Absorption Spectrometry(AAS,原子吸收光譜法)區分。AAS基于原子對光的吸收,而AES基于光的發射。
如需更深入的技術細節(如儀器結構、光譜幹擾等),可參考分析化學教材或專業文獻。
