Our research aims to investigate the potential of using a combination of the ion exchangers Lewatit CNP LF (in H+ form) and AV-17-8 (in OH\u2212 form) as an interpolymer system, \u201cLewatit CNP LF@AV-17-8\u201d (X:Y), with varying mass ratios of X:Y to enhance the sorption efficiency of lutetium ions from nitrate solution. During the study, we used a range of analytical methodologies, including gravimetry, ultraviolet-visible (UV-VIS) spectroscopy, and inductively coupled plasma optical emission spectroscopy (ICP-OES). Our findings demonstrate that the interpolymer system \u201cLewatit CNP LF@AV-17-8\u201d (X:Y), with a mass ratio of 4:2, exhibited a significantly enhanced sorption rate of Lu3+ ions (42%) compared to the individual Lewatit CNP LF (6:0) (25%) and the individual AV-17-8 (0:6) (21%) over a 48 h period. Moreover, this interpolymer system has demonstrated notable conformity to the Freundlich adsorption model, highlighting its performance as an effective sorbent for lutetium (III) ions. Notably, our study presents a novel utilization of the interpolymer system \u201cLewatit CNP LF@AV-17-8\u201d (4:2), with an adsorption capacity of 221.05 mg\/g, to enhance the recovery of lutetium ions. The research findings demonstrate its potential for enhancing the recovery of REE.<\/jats:p>","DOI":"10.3390\/polym16020220","type":"journal-article","created":{"date-parts":[[2024,1,12]],"date-time":"2024-01-12T03:54:34Z","timestamp":1705031674000},"page":"220","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Enhanced Lutetium Ion Sorption from Aqueous Solutions Using Activated Ion Exchangers"],"prefix":"10.3390","volume":"16","author":[{"given":"Talkybek","family":"Jumadilov","sequence":"first","affiliation":[{"name":"Bekturov Institute of Chemical Sciences, 106 Sh.
