Abstract

The stability of emulsions, containing tri-n-octylamine and di-n-octylamine salts in the organic phase and nitric acid in the aqueous phase has been studied. Optimal conditions for the extraction of Am(III) and Am(IV) phosphorus tungstate complexes with such emulsions have been determined. Emulsion membrane extraction is shown to be more effective for this purpose than conventional liquid extraction.
