<p>Process for the selective extraction of actinides (III) using amides having a nitrogenous heterocyclic substituant of the formula (I) or (II), in which R<1> is an alkyl or alkoxy group or a hydrogen atom, R<2> and R<3> which are the same or different, are a hydrogen atom, an alkyl group or an alkoxy group, and R<4> is a hydrogen atom or a group of the formula (a) in which R<5> and R<6> being the same or different, are a hydrogen atom, an alkyl group or an alkoxy group. By virtue of this process, actinides (III) can be separated from lanthanides (III).</p> |
