Abstract

1. Способ реэкстракции плутония из органического раствора трибутилфосфата (ТБФ), содержащего плутоний в четырехвалентном состоянии, в водный азотнокислый раствор путем контактирования указанного органического раствора с водным раствором, содержащим азотную кислоту и карбогидразид в качестве восстановителя, переводящего плутоний в трехвалентное состояние, отличающийся тем, что в состав восстановительного реэкстрагирующего раствора плутония вводят аминокарбоновую кислоту.2. Способ по п.1, отличающийся тем, что в качестве аминокарбоновой кислоты используют глицин с его концентрацией от 0,2 до 0,5 моль/л в растворе восстановителя.3. Способ по п.1, отличающийся тем, что в растворе восстановителя поддерживают содержание азотной кислоты от 0,25 до 1,5 моль/л.1. A method for re-extraction of plutonium from an organic solution of tributyl phosphate (TBP) containing plutonium in a tetravalent state into an aqueous nitric acid solution by contacting the specified organic solution with an aqueous solution containing nitric acid and carbohydrazide as a reducing agent, which converts plutonium into a trivalent state, characterized in that, that aminocarboxylic acid is added to the composition of the reducing stripping solution of plutonium. 2. The method according to claim 1, characterized in that glycine is used as the aminocarboxylic acid with a concentration of 0.2 to 0.5 mol / l in the reducing agent solution. The method according to claim 1, characterized in that the content of nitric acid in the solution of the reducing agent is maintained from 0.25 to 1.5 mol / l.
