Actinide extraction chemistry with the amine type of extractants

The extraction chemistry of the actinide ions and the inorganic acids with amides, N,N-dialkylamides (RRNCOR') and N,N'-tetraalkyl 2-alkyl propane diamides (RR'NCO)2 CHR'') is reviewed. Examples of application of those extractants in the separations for the nuclear industry are given. The monoamides are advantageous alternative to tributylphosphate and the diamides useful for the alpha TRU wastes decontamination. The most interesting aspect of these extractants are the innocuity of their radiolytic products and the possibility to incinerate the used solvents without large amounts of inorganic residues as for the organophosphorus extractants
