| Abstract: | s: The test sample is decomposed by strong hydrochloric acid and peroxide, the copper content isdetermined before the tungsten is deposited and separated. Experiment indicates that after adding ammonia the tungsten′s disturbance can be eliminated so the copper content can be determined by iodine method in the mixed tungsten copper powder. |
