A method for the separation and determination of neptunium in uranium-- fission product mixtures uses a twocycle extraction system. Neptunium is oxidized to 6+ with permanganate and quantitatively extracted as a nitrate complex into methyl isobutyl ketone from an acid-deficient aluminum nitrate salting solution containing tetrapropylammonium nitrate. Neptunium is stripped from the ketone phase and simultaneously reduced to 4+ by contact with ferrous chloride--hydroxylamine solution, then quantitatively extracted into thenoyltrifluoro acetone-xylene. The extraction of uranium and plutonium is less than 0.1 and O.O1%, respectively. Ruthenium and zirconium, the only 80-day cooled fission products which follow the neptunium, are decontaminated to greater than 1 x 10/sup 4/.
