FIELD: radiochemical engineering. ^ SUBSTANCE: extraction mixture comprises 0.1-1.2 M solution of bidentate organophosphorous extractant in polar fluorinated diluent, the former, more particularly, being dihexyl N,N-diethylcarbamoylphosphonate and the latter bis-tetrafluoropropyl ether of diethylene glycol. Extraction mixture may include 0.1-1.2 M phenyloctyl-N,N-diisobutylcarbamoylphosphine oxide in polar diluent as bidentate organophosphorous extractant, wherein polar diluent is m-nitrobenzotrifluoride/trialkyl phosphate mixture and content of trialkyl phosphate in extraction mixture is 0.3-1.1 M. ^ EFFECT: enabled simultaneous extraction of transplutonium, rare-earth elements, and uranium. ^ 2 cl, 2 dwg, 2 tbl, 4 ex |
