| Abstract: | The soil sample was digested by HNO3-H2SO4-HClO4 mixed acid. The content of arsenic in soil was detected by hydride generation atomic fluorescence spectrometry. Results showed that the detection limits was 0. 01 μg/L for arsenic. The recovery rates of spiking standards for arsenic was in the range of 91.2% - 104%. The relative standard deviation of arsenic was less than 3. 1%. The method could obtain the precise and accurate result and meet the need of practical analysis. |
