摘要
用 AFS-2 2 0 1双道氢化物发生原子荧光法测定水、土壤样品中的砷含量 ,方法简捷、快速、准确 ,二次污染物少。HNO3浓度大于 5 ppm时 ,对测量结果有影响。主机通过与微机相联可直接得出监测数据 ,大大减轻了监测人员的工作量 ,测定结果令人满意。
The Arsenic contents in water and soil are determined continuously by AFS 2201 dual channel fluorescence spectrometry The method is simple, quick, accurate, and little pollution The concentration of HNO 3 can affect on the determined results of As when the concentration is more than 5 ppm
