Тип записи:Публикация, НЕОДИМ ИОНДАРЫН СІҢІРУГЕ АРНАЛҒАН МОЛЕКУЛАЛЫҚ ТАҢБАЛЫ ПОЛИМЕРЛЕР СИНТЕЗІ(2020-01-01); 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.

SuberlyakThe 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.

Тип записи:Публикация, SELECTIVITY OF INTERPOLYMER SYSTEMS WITH RESPECT TO LANTHANUM IONS(2021-03-14); ; ; 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% - Некоторые метрики заблокированы вашиминастройками согласия

Тип записи:Публикация, ОСОБЕННОСТИ ДИСТАНЦИОННОГО ВЗАИМОДЕЙСТВИЯ ГИДРОГЕЛЕЙ ПОЛИАКРИЛОВОЙ КИСЛОТЫ И ПОЛИЭТИЛЕНИМИНА(2021-04-17); ; ; J.V. GraẑulevičiusThe remote interaction between a weak polyacrylic acid polyelectrolyte (gpac) and a weak polyethyleneimine polybase (gpei) is studied as a function of time at their different molar ratios and states in an aqueous medium. To predict the possibility of activation of the studied hydrogels, electrochemical properties were studied by conductometry and pH metry. During pH measurement, it was found that 24 hours of pH have the lowest values, indicating a high content of H+ ions in the aqueous medium. The dependence of the specific electrical conductivity, the maximum value at the ratio of 3:3 (PAC:PEI) and it coincides with the result of pH from the ratio of components. The obtained results indicate that significant changes in the electrochemical and conformational values of the initial macromolecules in the interpolymer system occur in this interpolymer system. Thus, studies have shown on the presence of a remote interaction between hydrogels and their mutual activation. With an increase in the content of one of the hydrogels in the solution, a significant increase in the swelling of hydrogels is observed in proportion to the concentration of the second component, which indicates their mutual activation.

Тип записи:Публикация, Effective Sorption of Europium Ions by Interpolymer System Based on Industrial Ion-Exchanger Resins Amberlite IR120 and AB-17-8(Multidisciplinary Digital Publishing Institute, 2021-07-09); Kondaurov Ruslan GennadievichThe research is aimed at checking the impact of a remote interaction phenomenon on growth of sorption properties of ion-exchange resins during sorption of europium ions. Industrial ion exchangers Amberlite IR120 and AB-17-8 were selected as objects for the study. Investigation was undertaken using the following physico-chemical methods of analysis: conductometry, pH-metry, colorimetry, Fourier transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA), and atomic emission spectroscopy. Remote interaction of the initial ion exchangers in the interpolymer system leads to their transition into highly ionized state due to formation of optimal conformation. Found that high ionization areas of Amberlite IR120 and AB-17-8 are the molar ratios Amberlite IR120:AB-17-8 = 4:2 and 1:5. The remote interaction effect provides significant increase of the following sorption properties: sorption degree, polymer chain binding degree, effective dynamic exchange capacity. A strong increase of the sorption properties (average increase for all time of remote interaction is over 50%) in the interpolymer system Amberlite IR120-AB-17-8 was observed with individual polymer structures of Amberlite IR120 and AB-17-8. The remote interaction phenomenon can be successfully used for effective modification of industrial ion exchangers for sorption of rare-earth metals.Цитирования (OpenAlex) 7Цитирования (OpenCitations) 6
