different extents in pure hexone and in solutions of hexone in organic solvents (
e.g., kerosene). In the extraction of the actinides, essentially all of the radioactive
fission products and the excess oxidant remained in the aqueous phase for ...

Radioactive Waste Management, Second Edition
Several solvent processes are available, and are described below. Hexone/
Redox solvent processes Hexone (methyl isobutyl ketone) is the solvent for the
Redox process, and sodium dichromate is the oxidizing agent added to the feed
nitrate ...

Aluminum nitrate salting agent is added, after which the solution is contacted with
hexone to extract the Pu(VI) and U(VI) in the organic phase and essentially all of
the radioactive fission products and the excess oxidant and its reduction ...

Radiochemistry of Neptunium
18 * Extraction with methyl isobutyl ketone (hexone) is based on the solvent
power of hexone for the covalent nitrates of the (VI) oxidation states. Hexone was
used for large-scale processing of irradiated nuclear fuels ("redox" process) but
has ...

The Radiochemistry of Niobium and Tantalum
Methyl isobutyl ketone (hexone) has been used to extract Nb and Ta fluorides in
the presence of HgS0^, HC1, and HN0^. Nb and Ta are completely extracted
from aqueous solutions 10 M in HF, 6 M in HgS0^ and 2.2 M in NH^F.^16' The ...

The name originates from the multiple reduction and oxidation stages alternately
applied to separate the plutonium and uranium. Basically, uranium (VI) and
plutonium (IV and VI) ions are soluble in the organic solvent hexone (methyl
isobutyl ...

Radiochemistry of Bismuth
Add 5 ml of 6-N HCl to the Bi(0H).j precipitate and transfer the solution to a 60-ml
separatory funnel. Wash the centrifuge tube with l0 ml of 6-N HCl and add the
washings to the separatory funnel. Add l5 ml of hexone and shake vigorously.

Methyl isobutyl ketone (hexone) is used as the solvent in this process, which is
also used to purify uranium from mining ores. Hexone, immiscible with water,
selectively extracts uranyl and plutonyl nitrates from the solution, if sufficiently
high ...
