原子吸收光譜法（Atomic Absorption Spectrometry, AAS）是一種用于測定樣品中特定金屬元素含量的高靈敏度分析技術。其核心原理基于基态原子蒸氣對特定波長光輻射的選擇性吸收。以下是詳細解釋：
基本原理
當處于基态的原子受到特定波長的光輻射時，會吸收能量躍遷至激發态。每種元素都有其獨特的吸收波長（共振線）。通過測量特定波長光被樣品原子蒸氣吸收的程度（吸光度），并與已知濃度的标準溶液進行比較，即可定量測定樣品中該元素的含量。其定量基礎遵循朗伯-比爾定律（Lambert-Beer's Law）：
$$
A = log(frac{I_0}{I}) = varepsilon b c
$$
其中，$A$ 為吸光度，$I_0$ 和 $I$ 分别為入射光和透射光強度，$varepsilon$ 為摩爾吸光系數，$b$ 為吸收光程長度，$c$ 為待測元素濃度。

原子吸收光譜法（Atomic Absorption Spectrometry，AAS）是一種用于元素定量分析的儀器分析方法，其核心原理是通過測量氣态基态原子對特定波長光的吸收程度來确定樣品中元素的含量。以下是詳細解釋：
原子吸收光譜法基于原子中電子能級躍遷的特性。當光源發出的特征輻射通過原子化後的樣品蒸氣時，基态原子會選擇性吸收與其能級差匹配的特定波長光，導緻光強度減弱。通過測量吸光度變化，可推算元素濃度。
根據朗伯-比爾定律，吸光度（A）與元素濃度（C）成正比： $$ A = KC $$ 其中，K為與實驗條件相關的常數。通過标準曲線法可定量未知樣品濃度。
例如，在環境監測中，流動注射氫化物原子吸收法可檢測河流沉積物的砷和汞，檢出限低至2ng/L，精密度和準确度均表現優異。
原子吸收光譜法通過基态原子的選擇性吸光實現元素定量，兼具高靈敏度與準确性，是痕量分析的重要工具。其技術分支（如氫化物法、石墨爐法）進一步擴展了應用範圍。
