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.

The maximum content of yttrium ions in the aqueous medium after sorption is observed at ratios of 3:3 and 4: 2 and the duration of remote interaction is 88 hours. At the same time, the content of yttrium in the aqueous medium after sorption is 60 mol.% and 56.4 mol.%, respectively. High values of the degree of binding of the polymer chain with respect to yttrium are observed at the ratios KU 2-8: AB-17-8=3:3 References [1] Jumadilov T.K., Abilov Zh.A., Kaldayeva S.S., Himersen H., Kondaurov R.G.

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.
