| Abstract: | In HCl medium, Se and As in groundwater are preconcentrated with sulfhydryl cotton. HNO 3 and HClO 4(5+1) are used to separate Se and As from Sulfhydryl cotton when heated. Se and As are determinated by hydride generated AFC. The method has the advantages of accuracy, precision and specificity. It accords with the demand of determination of groundwceter. |
