Separation of Praseodymium and Dysprosium by Solvent Extraction Using Fatty Acid as an Extractant Ⅱ |
| 초록 |
The separation of praseodymium and dysprosium has been carried out by solvent extraction with fatty acid in kerosene as a diluent. In our previous study, we had been studied the trend of separation of praseodymium and dysprosium depending on the carbon chain length and the pH of aqueous phase. According to the results, octanoic acid is the best extractant among fatty acid. In this study, the extractibility and the extraction efficiency of praseodymium and dysprosium are studied with various concentration of octanoic acid. We can get the highest extraction efficiency of them with 1.5 M octanoic acid as an extractant. |
