Claims (3)

1. Способ регенерации матрицы отработанной основной монообменной смолы в форме соли хлористого водорода и восстановления регенерирующего раствора, отличающийся тем, что он включает: а) пропускание регенерирующего раствора, содержащего третичный амин в амидном растворителе, через матрицу для регенерации отработанной смолы и образовании амидного раствора соли третичного амина с хлористым водородом; б) обработку полученного раствора безводным аммиаком для осаждения хлорида аммония и образования раствора, содержащего третичный амин в амидном растворителе: и в) отделение регенерирующего раствора от осадка.1. A method of regenerating a matrix of spent basic mono-exchange resin in the form of a salt of hydrogen chloride and recovering a regenerating solution, characterized in that it includes: a) passing a regenerating solution containing a tertiary amine in an amide solvent through a matrix for regenerating the spent resin and forming an amide salt solution tertiary amine with hydrogen chloride; b) treating the resulting solution with anhydrous ammonia to precipitate ammonium chloride and form a solution containing a tertiary amine in an amide solvent: and c) separating the regenerating solution from the precipitate. 2. Способ по п.1, отличающийся тем, что амидным растворителем является диметилацетамид, и третичным амином-три-н-бутиламин. 2. The method according to claim 1, characterized in that the amide solvent is dimethylacetamide, and the tertiary amine is tri-n-butylamine. 3. Способ по п.1, отличающийся тем, что отделенный регенерирующий раствор используется для регенерации дальнейших количеств отработанной основной ионообменной смолы в форме соли хлористого водорода. 3. The method according to claim 1, characterized in that the separated regeneration solution is used to regenerate further quantities of spent basic ion-exchange resin in the form of a salt of hydrogen chloride.
