Abstract—Maleic anhydride–styrene–1,4-di(4-isopropenylphenoxy)butane terpolymer was tested as sorbent for
treatment of aqueous solutions, including oil-ﬁ eld brines, to remove uranium salts.

Removal of heavy metal ions and radionuclides
from natural and wastewaters is an urgent problem [1,
2]. Recently particular attention in the development
of economically sound water treatment procedures
has been given to use of polymeric sorbents based on
styrene, divinylbenzene, acrylonitrile, vinylpyridine,
and other monomers containing various functional
groups capable of selective chemical binding of deﬁ nite
ions in the course of sorption [3–5].
The efﬁ ciency of recovering ions from a complex
aqueous system depends not only on the nature and
amount of the polymeric sorbent used, on the presence
of deﬁ nite functional groups in it, but also on pH of the
medium, which should be favorable for the sorption and
formation of surface complexes .
The goal of this study was to examine functional
properties of a newly developed synthetic sorbent,
hydrolyzed terpolymer of maleic anhydride, styrene,
and 1,4-di(4-isopropenylphenoxy)butane, toward UО
ions, to determine optimal conditions for the recovery
of these ions from aqueous solutions in relation to
various factors, and to evaluate the possibility of the
regeneration and reuse of the sorbent.
was prepared by radical copolymerization of large-ton-
nage monomers, maleic anhydride and styrene, with a
cross-linking comonomer, 1,4-di(4-isopropenylphe-
noxy)butane, at the component molar ratio of 55 : 35 :
10, respectively, in a solvating solvent (dioxane) in the
presence of a polymeric blowing agent, followed by
treatment with water . As polymeric blowing agent
we used a linear copolymer of maleic anhydride with
styrene (~4%). The water treatment of the copolymer
was aimed to convert anhydride groups into carboxy
