    As a result of the remote interaction of the studied hydrogels, their mutual activation occurs, leading to a significant change in their electrochemical and conformational properties. At certain ratios of acidic and basic hydrogels, there is a significant increase in the sorption of neodymium ions compared to the original hydrogels. These results indicate the emergence of ionized structures with optimal conformation. References [1] Alimbekova B.T., Korganbayeva Zh.K., Himersen H., Kondaurov R.G. and Jumadi- lov T.K. // J.

    In order to develop a selective technology for obtaining metal ions from water systems, molecular imprinted polymers (MIP) were synthesized and studied. In the course of the study, template MIPs Nd3+ (secondary polymer mesh) and pseudomatrix without a template (primary polymer mesh) were synthesized. The MIP obtained with the misprint of the neodymium (III) ion was obtained from two functional monomers of methacrylic acid and 4-vinylpyridine. Complex formation with matrix neodymium ions in the ionic interaction of two functional monomers is studied. References [1] Dzhumadilov T.K. Kondaurov R.G.

    The effect of the solvent/monomer (S/M) ratio on the structure and adsorption properties of microporous polymer particles imprinted with lanthanum and scandium ions is studied. Microporous particles imprinted with lanthanum and scandium ions were obtained from two functional monomers-methacrylic acid (MAC) and vinylpyridine (4-VP) - by forming a complex with the template ion of lanthanum and scandium by ion interactions. The selfassembled lanthanum/monomer complex was polymerized in the presence of an ethylene glycol dimethacrylate (EGDMA) crosslayer by suspension polymerization. The chemical structure, morphology, and adsorption capacity of microporous particles imprinted with lanthanum and scandium ions were analyzed by infrared spectroscopy. Molecular polymers showed high selectivity with respect to lanthanum and scandium ions. REFERENCES [1] Jiang Y., Kim D. // Chemical Engineering Journal. 166 (2011). P. 435-444. [2] Dam H.A., Kim D.

    SELECTIVITY OF INTERPOLYMER SYSTEMS WITH RESPECT TO LANTHANUM IONS

    The paper deals with the sorption of lanthanum ions by an interpolymer system consisting of sulfonic cation exchanger KU2-8 and anion exchanger AV-17-8. To predict the sorption activity of the intergel system, the mutual activation of the KU2-8 sulfonic cationite with the AV-17-8 anionite in the aqueous medium was initially studied. Due to the mutual activation of hydrogels in the course of their remote interaction, the polymer macromolecules pass into a highly ionized state, which leads to a significant increase in the degree of extraction of lanthanum ions from polymer hydrogels in intergel vapors as compared to the initial polymers. We calculated the degree of extraction of lanthanum ions by the interpolymer system KU2-8: AV-17-8, the degree of binding of the polymer chain (in relation to lanthanum ions) with the initial ion exchangers and the interpolymer system KU2-8: AV-17-8. Based on the data obtained, a comparative analysis of the sorption of lanthanum ions by individual sorbents and an interpolymer system was carried out within the limits of the ratio KU2-8: AV-17-8 = 5: 1–1: 5. It has been established that the maximum degree of sorption of lanthanum ions by the KU2-8: AV-17-8 interpolymer system is observed within the ratio KU2-8: AV-17-8 = 2: 4 at 48 hours of remote interaction of the interpolymer system and is 54.73 mol. %, at which the degree of binding of the polymer chain is 6.15%

    Many technological solutions contain valuable components as waste and can become an additional source of rare-earth elements to meet the needs of modern production. The development of technologies based on commercially available and cheap sorbents reveals the possibility for rare earth recovery from various solutions. This paper provides research on using a combination of KU-2-8 and AV-17-8 ion exchangers in different molar ratios for cerium ions sorption from its nitrate solution. The mutual activation of the ion exchangers in an aqueous medium provides their transformation into a highly ionized state by the conformational and electrochemical changes in properties during their remote interaction. The ion exchange dynamics of solutions were studied by the methods of electrical conductivity, pH measurements, and atomic emission analysis of the solutions. The research showed that the maximum activation of polymers was revealed within the molar ratio of KU-2-8:AV-17-8 equal to 3:3. In more detail, in comparison to AV-17-8, this interpolymer system showed an increase in the sorption degree by more than 1.5 times after 6 h of interaction. Moreover, compared with KU-2-8, the same interpolymer system showed an increase in the degree of cerium ions sorption by seven times after 24 h of interaction. As a result, the total cerium ions sorption degree after 48 h of sorption by individual KU-2-8 and AV-17-8 was 38% and 44%, respectively, whereas the cerium ions sorption degree by the same interpolymer system in the molar ratio 3:3 became 51%. An increase in the sorption degree of cerium ions by the interpolymer system in comparison with individual ion exchangers can be explained by the achievement of a high ionization degree of ion exchangers being activated in the interpolymer system by the remote interaction effect.

    Some technological solutions contain valuable components and can become an additional source of rare-earth elements to satisfy the current production demands. This research provides the study on using a combination of polyacrylic acid hydrogel (hPAA) and hydrogel of poly-4-vinylpyridine (hP4VP) in different molar ratios for praseodymium ions sorption from its nitrate solution. The mutual activation of the hydrogels in an aqueous medium provides their transformation into a highly ionized state by the conformational and electrochemical changes in properties during their remote interaction. The electrochemical properties of solutions were studied by the methods of electrical conductivity, and pH measurements of the solutions. The research showed that the maximum activation of hydrogels was revealed within the molar ratio of hPAA:hP4VP equal to 1:5. Moreover, the total praseodymium ions sorption degree after 24 hours of sorption by individual hPAA and hP4VP was 54 % and 47 %, respectively, whereas the praseodymium ions sorption degree by the hPAA–hP4VP intergel system in the molar ratio 1:5 became 62 %. A slight increase in the sorption degree of praseodymium ions by the intergel system in comparison with individual hydrogels can be explained by the achievement of a higher ionization degree of hydrogels being activated in the hPAA–hP4VP interpolymer system by the remote interaction effect.

    Phenomena of remote interaction in intergel systems polymethacrylic acid hydrogel – poly-4-vinylpyridine hydrogel (hPMAA-hP4VP) and polymethacrylic acid hydrogel – poly-2-methyl-5-vinylpyridine hydrogel (hPMAA-hP2M5VP) have been studied. It was found that there is a decrease of specific electric conductivity, pH and swelling degree of PMAA, P4VP, P2M5VP hydrogels during lanthanum ions sorption by the intergel systems. Significant increase of sorption properties (up to 30 %) in intergel systems comparatively with individual hydrogels of PMAA, P4VP, P2M5VP points to the fact of high ionization during mutual activation of the polymers. Maximum sorption of lanthanum ions occurs at the ratios of 17%hPMAA:83%hP4VP and 50%hPMAA:50%hP2M5VP. Data on obtained IR spectra evidence to the sorption of the rare-earth metal by these intergel systems. The obtained results show a significant importance of possible application of intregel systems based on rare-crosslinked polymer hydrogels of acid and basic nature for creation of new innovative sorption technologies in hydrometallurgy.
