| Abstract: | Ge in organic germanium (Ge-132) was determined by AAS with air-acetylene flame.The linear relationship is obtained in the concentration of 0-1.25mg/mL. The Precision of the method is 1. 2/00.The RSD is less than 2%. The average recovery is 99.5%. Impurities of lead and arsenic in Ge-132 were determined by zeeman graphite furnace AAS.(NH_4)_2HPO_4 Mg as matrix modifier was used to determine Pb.Pd as matrix modifier was used to determine As. The characteristic masses are 8-2pg and 8pg, respectively. The RSD are 2. 1% and 2. 2%, respectively. The mechanism of atomization were discussed. |
