| Abstract: |
| A new sample digestion method using a mixture of HNO3, H2SO4 and H3PO4 as dissolution solvent was developed and used to determine molybdenum in the extraction liquid for pressurized molybdenum oxide concentrate by spectrophotometry with thiocyanate. The testing conditions including reducing agent, acidity and color condition were optimized. The liquid samples were tested for several times and the relative standard deviations was less than 1%. The results indicated that the proposed method was simple, accurate, highly precise and has been successfully applied in the real production inspection process. |
