| titleOfInvention | Method for extracting lanthanide from lanthanum-actinium mixture and application |
| abstract | The invention relates to a method for extracting lanthanide from a lanthanum-actinide mixture, which comprises the following steps: adding acetate of lanthanide and actinide elements, or oxide, hydrochloride and nitrate of the lanthanide and actinide elements into acetic acid-based ionic liquid and a small amount of water, heating and stirring to dissolve the acetate, then cooling to separate out crystals, and filtering to realize the separation of the lanthanide and actinide elements. The invention takes the acetic acid group ionic liquid as a coordination agent and a crystallization separation medium, and realizes the separation of lanthanide and actinide by utilizing different coordination and crystallization behaviors of lanthanide and actinide in the ionic liquid. Compared with the traditional solvent extraction method, the method has the advantages of simple operation, greenness, sustainability, high selectivity and the like. |
