Description

Extraction of Sc, Ga, In, Tl, Mo, Zr, Sn, Sb, U, Th microamounts by solutions of diphenyl(dialkylcarbamoylmethyl)phosphine oxides in 1,2-dichloroethane from hydrochloric acid solutions depending on the structure of the extracting agent and hydrochloric acid concentration in the aqueous phase has been studied. In terms of their extractive capacity the compounds studied are superior to monodentate neutral organophosphoric extractants. Uranium extraction selectivity increases with alkyl radical substitution for hydrogen atom in methylene bridge of carbamoylmethylphosphine oxide molecules

Abstract (Russian)

Исследована экстракция микроколичеств Sc, Ga, In, Tl, Mo, Zr, Sn, Sb, U, Th растворами оксидов дифенил(диалкилкарбамоилметил)фосфинов в 1,2-дихлорэтане из солянокислых растворов в зависимости от структуры экстрагента и концентрации соляной кислоты в водной фазе. По экстракционной способности изученные соединения превосходят монодентатные нейтральные фосфорорганические экстрагенты. Селективность экстракции урана повышается при замещении атома водорода в метиленовом мостике молекулы карбамоилметилфосфиноксида алкильным радикалом
