Extraction has been studied of uranium(VI) from solutions of sodium tr
ifluoro-, trichloro-, and tribromo-acetates and sodium naphthalenesulf
onate with chloroform solution of diantipyrylmethane. Conditions of qu
antitative extraction and composition of the extracted uranium(VI) com
plex UO(2)LX(2) have been determined. Chemical features of the extract
ion process are discussed.
