摘　　要：采用蒸汽发生-原子荧光光谱法,分别在酒石酸和柠檬酸介质中分析山楂叶中砷A(s)、汞(H g)的含量,考察仪器操作条件、反应介质及共存离子等对测定As、Hg的影响.方法检出限为As:0.75μg k/g,Hg:0.034μgk/g.Trace elements As and Hg were determined in tartaric acid and citric acid, respectively, by vapor generation- atomic fluorescence spectrometry. The effect of instrument conditions, reaction conditions and coexistent ions were investigated. The proposed method had limits of 0.75 μg/kg of As and 0. 034μg/kg of Hg.
