It has been demonstrated that the chemical stability as well as sorption characteristics are determined by the resorcinol\/formaldehyde molar ratio and the solidification temperature. It has been also demonstrated that the sample synthesized at the resorcinol\/formaldehyde molar ratio of 1.8\/2.2 and solidified at 210 \u00b0C is characterized by the best sorption-selective characteristics and chemical stability. Under dynamic conditions, at feeding &gt;1000 bed volumes of a model solution with pH &gt; 13, the RFR 3-1 goes through six sorption cycles without noticeable changes in the sorption characteristics. The results are presented that demonstrate the possibility of RFR application in the decontamination of real LRW from Cs-137.<\/jats:p>","DOI":"10.3390\/gels7040239","type":"journal-article","created":{"date-parts":[[2021,12,1]],"date-time":"2021-12-01T03:12:56Z","timestamp":1638328376000},"page":"239","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Effect of the Resorcinol\/Formaldehyde Ratio and the Temperature of the Resorcinol\u2013Formaldehyde Gel Solidification on the Chemical Stability and Sorption Characteristics of Ion-Exchange Resins"],"prefix":"10.3390","volume":"7","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6833-0418","authenticated-orcid":false,"given":"Eduard","family":"Tokar","sequence":"first","affiliation":[{"name":"Institute of Chemistry, Far Eastern Branch, Russian Academy of Sciences, 159, Prosp. 100-Letiya Vladivostoka, 690022 Vladivostok, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mikhail","family":"Tutov","sequence":"additional","affiliation":[{"name":"Institute of Chemistry, Far Eastern Branch, Russian Academy of Sciences, 159, Prosp. 100-Letiya Vladivostoka, 690022 Vladivostok, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pavel","family":"Kozlov","sequence":"additional","affiliation":[{"name":"FSUE \u201cMayak Production Association\u201d, The Department of Chemistry and Chemical Technology, Prosp.
