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 - Некоторые метрики заблокированы вашиминастройками согласия

Тип записи:Публикация, FEATURES OF SORPTION OF CERIUM IONS BY THE INTERPOLYMER SYSTEM BASED ON AMBERLITE IR120 AND AB-17–8 ION-EXCHANGE RESINS(National Academy of Sciences of the Republic of Kazakhstan, 2023-03-31); 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 opens up the possibility of extracting rare earth elements from various solutions. The aim of this work is to study the effect on the process of sorption of cerium ions from the corresponding sulfates by individual Amberlite IR120, AB-17-8 ion exchangers and an interpolymer system based on them. The experiments were carried out using the following physicochemical methods of analysis: conductometry, pH-metry, colorimetry, and atomic emission spectroscopy. Ion exchangers in the interpolymer system undergo remote interaction with a further transition to a highly ionized state. An optimal conformation is formed in the structure of the initial ion exchangers. A significant increase in the ionization of ion exchange resins occurs at a molar ratio of Amberlite IR120:AB-17-8 = 3:3. With this ratio, a significant increase in sorption properties is observed due to the mutual activation of ion exchangers. The average increase in the sorption properties of cerium ions in the Amberlite IR120:AB-17-8 = 3:3 interpolymer system is more than 85% compared to Amberlite IR120 and almost 70% compared to AB-17-8. A possible reason for the high sorption is the maximum correspondence between the globes of the interlayer chain of Amberlite IR120 and AB-17-8 bond ions after their mutual activation in an aqueous medium.
