FIELD: chemistry.
SUBSTANCE: invention relates to use of aldoximes as agents of anti-nitrogen action during re-extraction re-extraction of plutonium. Invention can be used in any methods of processing spent nuclear fuel. As an anti-nitrogen agent in the operation of reducing re-extraction of plutonium, at least one aldoxime of formula R-CH=N-OH is used, where R denotes a linear or branched hydrocarbon chain with at least 4 carbon atoms.
EFFECT: invention enables to obtain an aqueous phase with high concentration of plutonium, as well as reduce the size of the apparatus used to carry out reductive re-extraction of plutonium.
