| Abstract: |
| The experiment adopts the enrichment and separation method of Pb-assaying.The DDO method is used to determine platinum and palladium simultaneously in High-grade nickel matte. Through researching the component of assaying,an appropriate make-up is put forward with the silicic acidity of 0.5. The method provides a high accuracy.The RSD is found to be less than 3.3% and recoveries are more than 98%. |
