“…This is probably due to the fact that in the Fe(II)‐PAR complex there is a hydroxyl group that can be involved in hydrogen bonding with a carboxyl group in MAA or a hydroxyl group in HEMA. Another possible mechanism for the formation of a prepolymerization complex is the interaction between MAA or HEMA (their anionic forms) with the cationic form of the Fe(II)‐PAR ([Fe(PAR)] + ) 29 . In the case of Fe(II)‐BP 3 , only the second type of interaction is realized ([Fe(BP) 3 ] 2+ ).…”

The effect of template species -Fe(II) complexes with 4-(2-pyridylazo)resorcinol or 2,2 0 -bipyridine as well as the functional monomers: acidic (methacrylic acid) and neutral (hydroxyethyl methacrylate) on the extraction efficiency and applicability of Fe(II) ion-imprinted polymers for iron speciation in surface waters is presented in this study. The polymers were synthesized by precipitation copolymerization of functional monomer, trimethylolpropane trimethacrylate (crosslinking agent) and 2,2 0 -azo-bis-isobutyronitrile (initiator) in the presence of template and characterized by elemental microanalysis, SEM and Brunauer-Emmett-Teller analyses. Extraction efficiency was examined by batch solid-phase extraction. The equilibrium experimental data of adsorption processes with different synthesized sorbents were fitted by both Langmuir and Freundlich isotherms and are discussed from the viewpoint of possible bond formation between monomer and template species and the stability of the prepolymerization complex. Pseudo-first-order and pseudo-second-order kinetic models were tested to elucidate the possible controlling mechanism of the sorption process for different sorbents. Under the optimum conditions pH 7 and equilibrium time of 30 min the highest extraction efficiency and selectivity toward Fe(II) was achieved for Fe(II) ion-imprinted polymer containing methacrylic acid and Fe(II)-4-(2-pyridylazo)resorcinol complex as a template. The analytical procedure for Fe speciation was developed and validated with this sorbent.

Growing concern over the hazardous effect of radionuclides on the environment is driving research on mitigation and deposition strategies for radioactive waste management. Currently, there are many techniques used for radionuclides separation from the environment such as ion exchange, solvent extraction, chemical precipitation and adsorption. Adsorbents are the leading area of research and many useful materials are being discovered in this category of radionuclide ion separation. The adsorption technologies lack the ability of selective removal of metal ions from solution. This drawback is eliminated by the use of ion-imprinted polymers, these materials having targeted binding sites for specific ions in the media. In this review article, we present recently published literature about the use of ion-imprinted polymers for the adsorption of 10 important hazardous radionuclides—U, Th, Cs, Sr, Ce, Tc, La, Cr, Ni, Co—found in the nuclear fuel cycle.

“…We paid special attention to the design and preparation of solid sorbents characterized by good sorption properties including high efficiency and fast kinetics of the sorption and desorption process of the analyte, and versatile in practice and application. Based on our previous experience [34], we have prepared two ion imprinted polymers based on the Cr(III)-1,10-phenanthroline complex, containing aromatic rings that can be easily arranged in the polymer matrix. For the synthesis of both IIPs, neutral functional monomer-styrene, aprotic solventacetonitrile, divinylbenzene as a cross-linking monomer and AIBN as an initiator were used in bulk polymerization.…”

In this work, a new solid phase extraction method for the determination of chromium species in water samples by electrothermal atomic absorption spectrometry was developed. For selective separation of Cr(III) ions under dynamic conditions, two ion imprinted polymers containing Cr(III)-1,10-phenanthroline complex (Cr(III)-phen) were prepared with the use of one (styrene, ST) or two (styrene and 4-vinylpyridine, ST-4VP) functional monomers. The physicochemical properties of those solid sorbents towards Cr(III) ions were studied and compared. It was found that Cr(III) ions were retained on the Cr(III)-phen-ST and Cr(III)-phen-ST-4VP polymers with high efficiency and repeatability (91.6% and 92.9%, RSD < 2%) from solutions at pH 4.5. The quantitative recovery of the analyte (91.7% and 93.9%, RSD < 4%) was obtained with 0.1 mol/L EDTA solution. The introduction of 4VP, an additional functional monomer, improved selectivity of the Cr(III)-phen-ST-4VP polymer towards Cr(III) ions in the presence of Cu(II), Mn(II) and Fe(III) ions, and slightly decreased the sorption capacity and stability of that polymer. The accuracy of procedures based on both polymeric sorbents was proved by analyzing the standard reference material of surface water SRM 1643e. The method using the Cr(III)-phen-ST polymer was applied for determining of Cr(III) ions in tap water and infusion of a green tea.
