| Abstract: | Phenylfluorone can react with germanium to form an orange -red complex in the medium of hydrochloric acid. Using Phenylfluorone as colour developing reagent and Tween - 80 as surfactant, germanium content in vegetable was determined by pectrophotometry. The wave - length was 512 nm and optimium experiment conditions were confirmed. Vegetable was digested by HNO3 -H2O2 and the content of germanium was 1.54 μg/g. |
