| Abstract: | To shoose suitable determination conditions for apparatus,effect of some reaction acid concentration the fluorescence signal were compared.Elimination of interference from some ions by L-cysteine–thiourea-tartaric acid solution,detection limit of the method is 0.08μg/g（n=12） for germanium,RSD is 4.8-9.6%（n=12） for germanium in 8 kinds soil national geological standard samples,togC is 0.002-0.015.The method is suitable for the determination in geological-chemical samples. |
