Synthesis and
properties strong base acrylate polyfunctional anion-exchange resins for
uranium extraction
Abstract
The investigations on
the synthesis of multifunctional acrylate strongly basic anion exchangers,
designed to extract uranium from underground leaching solutions, were carried
out. The conditions of the alkylation reaction were determined, when we get polyfunctional
anion-exchange resin which contains up to 55% of strongly basic groups. The
sorption properties of the anion exchanger were studied on the model solutions.
Comparative analysis of ion exchange characteristics with parameters famous
anion exchangers has shown that the capacity of alkylated multifunctional the
anion exchanger of uranium is not inferior to foreign models.
Key words: polyfunctional anion-exchange resins, ion
exchange resins, sorption of uranium.
