Abstract
Способ извлечения редкоземельных элементов из растворов и пульп, содержащих железо(III) и алюминий, включающий сорбцию редкоземельных элементов на сорбенте, отличающийся тем, что в качестве сорбента используют амфолит с иминодиацетатными функциональными группами и сорбцию проводят после предварительной нейтрализации или закисления раствора (пульпы) до рН 4÷5 любым щелочным или кислым агентом, с дальнейшим введением амфолита в раствор (пульпу) без отделения твердой части, при соотношении ионит: раствор 1:50÷1:150, времени контакта фаз 3÷6 ч, в присутствии восстановителя. A method for extracting rare earth elements from solutions and pulps containing iron (III) and aluminum, including the sorption of rare earth elements on a sorbent, characterized in that an ampholyte with iminodiacetate functional groups is used as a sorbent and the sorption is carried out after preliminary neutralization or acidification of the solution (pulp) to pH 4 ÷ 5 with any alkaline or acidic agent, with further introduction of ampholyte into the solution (pulp) without separating the solid part, with the ratio of ion exchanger: solution 1: 50 ÷ 1: 150, contact time of the phases 3 ÷ 6 h, in the presence of a reducing agent.
