N,N-dialkyl substituted alkyl amides are known to be good extractants of some actinides such as U, Pu, and Th. Their stability is comparable to that of TBP, and their degradation products do not interfere as do the degradation products of TBP. On the other hand, the principal disadvantage of the amides is their tendency to form poorly soluble U adducts in organic diluents. A systematic investigation has been carried out on the extractive behavior of two typical alkyl amides of different structures with respect to the actinide ions UO/sub 2/ /sup 2+/, Th /sup 4+/, Np /sup +4/, Pu /sup +4/, NpO /sub 2/ /sup 2+/, PuO /sub 2/ / sup 2+/, Pu /sup 3+/, and Am /sup 3+/, as well as with respect to the most significant fission products. The results obtained have been compared with those obtained using TBP in the same experimental conditions, verifying the applicability of amides in the separation of U from Th.
