Abstract—The sorption activity of polysulfones derived from tris(diethylamino)diallylaminophosphonium
tetraﬂ uoroborate in recovery of chromium and rhenium ions from hydrogen chloride and ammonia solutions was
Polymeric sorbents of diverse classes are widely
used for metal preconcentration [1, 2]. Synthesis of such
sorbents for selective recovery of deﬁ nite ions from
multicomponent solutions is of much practical interest.
Certain speciﬁ c features in sorption are exhibited by
phosphorus-containing complexing ion exchangers,
which makes promising their synthesis . In view of
success in synthesis and application of organophosphorus
extractants showing high potential as complexing
agents, much attention is given to polymeric phosphorus
derivatives. As compared to many known sorbents,
these compounds exhibit a wider range of properties.
It is known that the presence in organophosphorus
complexing molecules of N, O, and S heteroatoms
tending to coordination with metals makes these agents
speciﬁ c to deﬁ nite cations . Owing to selective action,
phosphorylated polyamines can be successfully used for
fractional determination and isolation of cations present
in difﬁ cult-to-separate combinations. Large difference in
the strength of complexes of phosphorylated polyamines
with d-transition and rare-earth metals considerably
simpliﬁ es their separation. Therefore, studies of the
sorption ability of novel phosphorylated polyamines are
With the aim to prepare new potential sorbents, we
synthesized polysulfones derived from tris(diethyl-
amino)diallylaminophosphonium tetraﬂ uoroborate and
examined their sorption activity.
ﬂ uoroborate (EAAP–ВF
) was prepared by the proce-
dure described in  in 70.1% yield. The product pu-
rity was checked by elemental analysis and by
Н NMR spectroscopy.
Sulfur dioxide was dried by passing through

The initiator used in this study, azobis(isobutyronitrile)
(AIBN), and the solvents, dimethyl sulfoxide (DMSO),
methanol, and tetrahydrofuran (THF), after puriﬁ cation
by standard procedures had characteristics agreeing
with reference data.
Copolymerization of diallylaminophosphonium salts
was performed in solution in the presence of
the initiator in a glass vessel . The polymers were
puriﬁ ed by twofold reprecipitation from solution in
appropriate solvent into the precipitant (THF), after
which they were washed with THF and vacuum-dried to
constant weight at 50°С. The copolymer compositions
were calculated from the results of elemental analysis.
The NMR spectra were recorded with a Bruker АМ-
300 spectrometer operating at 300 MHz for

С NMR spectra were recorded
in the broadband proton decoupling and JMOD
modes. As solvent we used DMSO-d
