Ion-Exchange Separation and Concentration of Ions of Rare-Earth Elements on Fibrous Sorbents

Abstract:

Acid-base properties and selectivity of absorption such ions as REE (Eu^3+, 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.
