| Abstract: | The samples were digested by microwave digestion,and determinated by hydride atomic fluorescence method.The result indicate that,the fluorescence intensity is linear with the concentration of arsenic in the range of 0～20 μg/L,the related coefficient is 0.999 7,the detection limit is 0.008 8 μg/L and the recovery for As of the method is between 95%～105%. |
