Abstract
[Objective] The aim was to develop a rapid,simple method for determination of arsenic and mercury in soil samples by atomic fluorescence spectrometry.[Method] The method for determination of As and Hg in soil by combined atomic fluorescence spectrometry and microwave digestion was used.[Result] The concentration curve was linear within the range of 0-80.0 μg/L of As and 0-8.0 μg/L of Hg,and the detection limits of As and Hg was 0.036 μg/L and 0.015 μg/L,respectively.The precision for elevenfold determination of As at 40.0 μg/L level and Hg at 4.0 μg/L level were 1.1% and 2.2%(RSD),respectively.Recoveries of 103.0%-106.6% for As and 90.0%-95.0% for Hg were obtained for there soil samples.[Conclusion] The proposed method has the advantages of simple operation,high sensitivity,and high efficiency;it was successfully used for determination of As and Hg in soil samples.
