- Abstract
- Extraction of uranium, thorium, and lanthanide(III) ions from nitric acid solutions with mixtures of dinonylnaphthalenesulfonic acid and N-(diphenylphosphoryl)-N'-n-propylureas containing imidazolyl, diethylamino, pyrid-2-yl, and 2-oxopyrrolidine fragments has been studied in organic solvents. Considerable synergetic effect on extraction of metal ions with mixtures of dinonylnaphthalenesulfonic acid and N-(diphenylphosphoryl)-N'-[3-(2-oxopyrrolidino)propyl]urea has been revealed. Stoichiometry of extracted complexes has been determined. Effect of extractant strucuture, organic diluent nature, and HNO3 content in aqueous phase on extraction efficiency of metal cations into organic medium has been accessed.
