| Abstract: |
| A method for the determination of germanium in germanium concentrate by inductively coupled plasma emission spectrometry (ICP-OES) was established. The sample was digested in nitric acid , hydrofluoric acid, and phosphoric acid. The detection limit of germanium was 0.006 g/mL, the lower limit was 0.020 g/mL, and the range was 1%-15%, which was consistent with the classical potassium iodate titration method. The relative standard deviation (SRD) less than 3% (n=11), the standard recovery rate is 98%~101%, which can meet the requirements of rapid determination and batch processing of germanium content in germanium concentrate. |
