Procédé de séparation des actinides et des lanthanides à partir d'une phase liquide provenant du retraitement de combustibles nucléaires usés |
摘要 |
<p>A process for the separation of actinides and lanthanides from a liquid phase originating from the reprocessing of spent nuclear fuels comprises bringing an organic phase of actinides An and lanthanides Ln into contact 3 with a first aqueous solution (HNO3 or NO3- > 0.1 mo1.1-1) comprising a hydrophilic organic complexing agent for actinides in order to extract An(III) from this first solution. Ln(III) can subsequently be recovered in a second aqueous solution 5. The complexing agent can be 2,6-bis(5,6-dimethy1-1,2,4-triazin-3-y1)-pyridine.</p> |
