Description

Distribution of scandium in the system of 2-[(di(2-hydroxyethyl)amino)methyl]-4-nonylphenol (HEAP) - aqueous chloride solutions is studied. Effect of HCl concentration, salting-out (NaCl) concentration, phase contact time on scandium distribution between aqueous and organic phases is investigated. Extraction isotherm is obtained. It is shown that NaCl introduction increases distribution coefficients of scandium and HEAP. Conditions of scandium reextraction are studied and possible way is proposed to regenerate extractant after reextraction stage

Abstract (Russian)

Изучено распределение скандия в системе 2-[(ди(2-гидроксиэтил)амино)метил]-4-нонилфенол (ГЭАФ) - хлоридные водные растворы. Исследовано влияние концентрации HCl, высаливателя (NaCl), времени контакта фаз на экстракцию скандия. Получена изотерма экстракции. Показано, что введение NaCl увеличивает коэффициенты распределения скандия и ГЭАФ. Изучены условия реэкстракции и предложен возможный путь регенерации экстрагента после стадии реэкстракции
