Resins were synthesized through the polycondensation of resorcinol and formaldehyde in an alkaline medium at a molar ratio of 1.8\/2.2 and a temperature of 210 \u00b0C. The Cs-137 distribution coefficients on RFRs in alkaline solutions simulating LRW were above 103 mL\/g under static sorption conditions. In a model solution with pH 11, the full dynamic sorption capacity of non-porous RFR was 0.178 mmol\/g. The values of the full dynamic sorption capacities of porous RFRs were 0.274 and 1.035 mmol\/g for resins obtained with calcium carbonate and toluene as templates, respectively. When the sizes of RFR beads increased two-fold, the volume until 5% cesium breakthrough decreased by 20\u201340%. The most pronounced beneficial effect of the RFR\u2019s porosity was observed at flow rates from 25 to 50 BV\/h. It was shown that the negative effect of metal cations on Cs-137 uptake increases in the following order: Na+ &lt; Mg2+ &lt; Ca2+ &lt; K+. The number of bed volumes of LRW-simulating solution decontaminated with RFRs until 5% cesium breakthrough was above 450; that is higher than the value of known commercially available analogs. The latter shows that the developed RFRs are promising for application in technological schemes of alkaline LRW processing.<\/jats:p>","DOI":"10.3390\/molecules27248937","type":"journal-article","created":{"date-parts":[[2022,12,16]],"date-time":"2022-12-16T02:54:02Z","timestamp":1671159242000},"page":"8937","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Removal of Cs-137 Radionuclide by Resorcinol\u2013Formaldehyde Ion-Exchange Resins from Solutions Simulating Real Liquid Radioactive Waste"],"prefix":"10.3390","volume":"27","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, Prosp. 100-letiya Vladivostok, 159, 690022 Vladivostok, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mikhail","family":"Tutov","sequence":"additional","affiliation":[{"name":"Institute of Chemistry, Far Eastern Branch, Russian Academy of Sciences, Prosp. 100-letiya Vladivostok, 159, 690022 Vladivostok, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4954-0422","authenticated-orcid":false,"given":"Svetlana","family":"Bratskaya","sequence":"additional","affiliation":[{"name":"Institute of Chemistry, Far Eastern Branch, Russian Academy of Sciences, Prosp. 100-letiya Vladivostok, 159, 690022 Vladivostok, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2599-2213","authenticated-orcid":false,"given":"Andrei","family":"Egorin","sequence":"additional","affiliation":[{"name":"Institute of Chemistry, Far Eastern Branch, Russian Academy of Sciences, Prosp. 100-letiya Vladivostok, 159, 690022 Vladivostok, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,15]]},"reference":[{"key":"ref_1","first-page":"18","article-title":"Stabilization of Thermophysical State and Survey of Some Tanks in Storage Facilities of High-Activity Pulps at FSUE \u201cPA \u201cMayak\u201d\u201d","volume":"4","author":"Logunov","year":"2011","journal-title":"Probl.
