| Abstract: | In this paper, the enrichment conditions for ultratrace germanium with tannic cellulose isdescribed. The effects of 36 ions on the determination of Ge by hydride generation (in phos-phoric acid) ICP-AES as well as their eliminations are studied. The method has been applied tothe determination of Ge in Groundwater with satisfactory result. The detection limit is 15ng/L. |
