Method for separating actinides from lanthanides |
| abstract |
(57) [Abstract] [Object] The present invention relates to a method for separating an actinide from a lanthanoid by selectively extracting the actinide in an organic solvent containing propanediamide. The invention relates to the addition of a thiocyanate, for example ammonia thiocyanate, to an aqueous nitric acid solution containing actinides and lanthanoids and subsequently adding at least one propanediamide, for example 2- Organic solvent containing a quaternary ammonium salt such as a mixture of tetradecyl-N, N'-dimethyl-N, N'-dibutyl-propanediamide and optionally trilaurylmethylammonium (TMA) thiocyanate or quaternary ammonium thiocyanate Contacting. Use of the present invention makes it possible to increase the partition coefficient D M for actinoids (Am) and lanthanoids (Eu, Ce) and achieve a high actinoid / lanthanoid separation factor. |
