Ion-exchange separation and concentration of ions of rare-earth elements on fibrous sorbents L. A. Bobkova, L. N. Skvortsova, L. B. Naumova, G. V. Kashkan

Contributor(s): Bobkova, Lyudmila A | Naumova, Lyudmila B | Kashkan, Galina V | Skvortsova, Lidiya NMaterial type: ArticleArticleSubject(s): редкоземельные металлы | амфолиты | комплексообразование | селективность | сорбция | разделениеGenre/Form: статьи в журналах Online resources: Click here to access online In: Key engineering materials Vol. 670. P. 270-275Abstract: Acid-base properties and selectivity of absorption such ions as REE (Eu3+, Gd3+, Nd3+, Yb3+) from solutions with various ionic force by the fibrous ampholytes PAN-FOSPAN and PAN-IDUC are investigated. PAN-FOSPAN shows the greatest selectivity to ions of REE. This fact can be used for division and the subsequent definition of ions. PAN-IDUC as a high selective fibrous sorbent after alkaline treatment is perspective one for absorption of the REE sum.
