Zusammenfassung:Extraction mixture (A), to recuperate the elements belonging to actinides from acid solutions, comprises: either a solution of an organic extraction agent (I) of bidentate phosphorus (dihexyl-N,N-diethylcarbamoylphosphonate) in a polar thinner (II) (bis-tetrafluoropropylic ether of diethyleneglycol); or a solution of (I) (phenyloctyl-N, N-diisobutylcarbamoylphosphine oxide) in (II) (mixture of metanitrobenzotrifluoride and trialkyl phosphate). Extraction mixture (A), to recuperate the elements belonging to actinides from acid solutions, comprises: either a solution of an organic extraction agent (I) of bidentate phosphorus (consisting of dihexyl-N, N-diethylcarbamoylphosphonate) in a polar thinner (II) (i.e. bis-tetrafluoropropylic ether of diethyleneglycol), where (I) is 0.1-1.2 M/l and (II) is rest; or a solution of (I) (consisting of phenyloctyl-N, N-diisobutylcarbamoylphosphine oxide) in (II) (i.e. mixture of metanitrobenzotrifluoride (III) and trialkyl phosphate), where the content of (I) is 0.1 - 1.2 M/l, tributyl phosphate is 0.3-1.1 M/l and (III) is rest.
