Description

For determination of optimal conditions of isolation, separation and concentrating of lanthanides investigation of their separation in self-oscillating systems. The basic idea of investigation is possibility of use of nonstationary nonequilibrium extraction in extraction cascade. The simplest model of extraction cascade is two reactors combined by liquid membrane which is organic phase - 0.5 M TBP in tetradecane. It is established that distribution coefficients of the hardest for separation elements Pr and Nd increase by several times as compared with stationary extraction methods of lanthanide separation

Abstract (Russian)

Для определения оптимальных условий разделения, выделения и концентрирования лантанидов проведено исследование их разделения в колебательных системах. Основная идея исследования - возможность использования нестационарной неравновесной экстракции в экстракционном каскаде. Простейшей моделью экстракционного каскада являются два реактора, соединенные жидкой мембраной, которой явилась органическая фаза - 0.5 М ТБФ в тетрадекане. Установлено, что коэффициенты разделения наиболее трудноразделимых элементов Pr и Nd увеличиваются в несколько раз по ставнению со стационарными методами разделения лантанидов
