Determination of As(Ⅲ) and As(Ⅴ) in water samples by NAA after extraction and coprecipitation
The neutron activation analysis of As(Ⅲ) and As(Ⅴ) contents in water samples is described. A separation method of inorganic arsenic As(Ⅲ) and As(Ⅴ) in water is studied using 76 As as an indicator. The APDC-CCl 4 extraction system is used in the separation of As(Ⅲ) and As(Ⅴ)
and inorganic arsenic in water samples is then coprecipitated by Fe(OH) 3. After filtering and parching the collected sediment can be analyzed by NAA directly.
