Description

Extraction of lanthanide(III) nitrates (La-Sm) by 1.83 mol/dcm3 TBP solutions in hexane and tetradecane at 298.15 K is studied. Extraction of lanthanide(III) nitrates by TBP solutions in hexane occurs in two-phase systems, and by TBP solutions in tetradecane - in two- and three-phase systems (with stratification of organic phase). Mathematical description of the extraction processes is done

Abstract (Russian)

Изучена экстракция нитратов лантанидов(III) (La-Sm) растворами 1.83 моль/дм3 ТБФв гексане и тетрадекане при 298.15 K. Экстракция нитратов лантанидов(III) растворами ТБФ в гексане происходит в двухфазных системах, а растворами ТБФ в тетрадекане - в двух- и трехфазных системах (с расслоением органической фазы). Проведено математическое описание процессов экстракции в многофазных системах
