| Abstract: | In this paper,the group separation of rare-earth element is studied by the method of solid extraction with P507 as extraction agent and paraffin as solvent. In the system of 0. 25 mol. L-1 nitric acid, it is pussible that the group separation of rare--earth element with P507 and paraffin as extraction agent. |
