Abstract
This invention relates to a process of recovering trivalent actinides, trivalent lanthanides or mixtures thereof from an aqueous acid solution by contacting the aqueous solution with an organic solution containing the diamides of the formula: ##STR1## where R is C.sub.2 -C.sub.10 alkyl. This process affords a good extraction efficiency level for the recovery of lanthanides and actinides, both of which are present in the trivalent state, or mixtures thereof, from installations for the reprocessing of irradiated nuclear fuels.
