| Abstract: | The sample is dissolved in aqua regia and perchloric acid. Perchloric acid and hydrochloric acid are selected as a determination medium, and their acidity is controlled reasonably . Then Ag in the copper concentrate is determinated by the atomic absorption spec-trophotometry. The method is simple and rapid, and it is easily grasped. The test results show that the detection limit is 0. 0026 mg/L, the recovery is 97.3%~102.5% and the vari-able coefficient is less than 3. 82%. |
