Abstract

Simultaneous determination of As and Hg by the hydride generation dual-channel atomic fluorescence spectrometry was developed.The optimization of the atomizer construction and parameters for hydride generation and fluorescence detection systems was carried out.Under the optimized conditions,the detection limits for As and Hg were 0—10μg/L and 0—1μg/L,respectively.The method has a wide linear range(As 0—10μg/L and Hg 0—1μg/L).In addition,the recovery rate varies from 96.0% to 101.0% for As and from 97.0% to 103.7% for Hg.
