Liquid–liquid extraction of trivalent americium from carbonate and carbonate–peroxide aqueous solutions by methyltrioctylammonium carbonate in toluene
Liquid–liquid extraction (LLE) of microamounts of americium(III) from Na 2 CO 3 and Na 2 CO 3 –H 2 O 2 aqueous solution using methyltrioctylammonium (MTOA) carbonate in toluene has been studied. The distribution ratio of americium(III) into the organic phase can reach values of > 200 from aqueous...
