Claims (4)

1. Способ регенерации трибутилфосфата, включающий обработку органического раствора щелочным водным раствором, отличающийся тем, что трибутилфосфат обрабатывают 1,5 - 2,5 моль/л раствором гидроксида натрия и/или калия в присутствии многоатомного спирта при молярном соотношении примесь металла : многоатомный спирт, равном 1 : 3,5 - 40, с последующим разделением фаз и возвращением реэкстрагента в начало процесса регенерации.1. A method for the regeneration of tributyl phosphate, comprising treating the organic solution with an alkaline aqueous solution, characterized in that the tributyl phosphate is treated with 1.5 to 2.5 mol / L sodium hydroxide and / or potassium hydroxide solution in the presence of polyhydric alcohol at a molar ratio of metal: polyhydric alcohol, equal to 1: 3,5 - 40, with the subsequent separation of the phases and the return of the stripping agent to the beginning of the regeneration process. 2. Способ регенерации трибутилфосфата по п.1, отличающийся тем, что в качестве многоатомного спирта используют сорбит или ксилит. 2. The method of regeneration of tributyl phosphate according to claim 1, characterized in that sorbitol or xylitol is used as the polyhydric alcohol. 3. Способ регенерации трибутилфосфата по пп.1 и 2, отличающийся тем, что щелочной реэкстракт подкисляют минеральной кислотой до выпадения осадка, и выделяющийся осадок отделяют. 3. The method for the regeneration of tributyl phosphate according to claims 1 and 2, characterized in that the alkaline re-extract is acidified with mineral acid until a precipitate forms, and the precipitate formed is separated. 4. Способ регенерации трибутилфосфата по пп.1 - 3, отличающийся тем, что в реэкстракт вводят гидроксид натрия и/или калия до исходной концентрации и возвращают в начало процесса регенерации. 4. The method of regeneration of tributyl phosphate according to claims 1 to 3, characterized in that sodium and / or potassium hydroxide is introduced into the re-extract to the initial concentration and returned to the beginning of the regeneration process.
