Abstract
Sorption of lanthanum, yttrium and ytterbium from solutions of mineral acids with sulfonic KU-2
was studed. The coefficients of distribution of rare earth elements during sorption of KU-2 from solutions of
mineral acids - nitric, hydrochloric and phosphoric was obtained. Determined that the equilibrium is reached
within 60 minutes of contact of the ion exchanger and the solution temperature does not significantly affect
the distribution ratio of the REE, which depends only on the nature of the REE. The experiments confirmed
that the strong acid cation resin KU-2 effectively absorbs the rare earth elements (REE), indicating that the
prospects of its use as a sorbent at extraction of REE from industrial wet process phosphoric acid.
