Description

The synergistic solvent extraction of 13 lanthanoids with mixtures of 8-hydroxyquinoline (HQ) and the crown ethers, 18-crown-6 and benzo-18-crown-6 (S) in 1,2-dichloroethane has been studied. The composition of the extracted species was determined as LnQ3·S. The values of the equilibrium constant and separation factor were calculated. The effect of the synergistic agent on the extraction process has been discussed

Abstract (Russian)

Изучена синергетическая экстракция 13 лантаноидов смесью 8-гидроксихинолина (HQ) и краун-эфиров (18-краун-6, бензо-18-краун-6) (S) в 1,2-дихлорэтане. Состав комплексов определен как LnQ3·S. Рассчитаны величины констант равновесия и факторы разделения. Обсуждается влияние синергетических агентов на процесс экстракции
