Research on iodine and its ion removal from water has attracted a great deal of interest due to increased concentrations in the environment and acute toxic effects, e.g., in human thyroid cells. In this work, the iodide removal performance of two high-surface-area resorcinol\u2013formaldehyde-based carbon aerogels was studied under acidic conditions. The BET surface area was 790 m2\/g (RF_ac) and 375 m2\/g (RMF-GO), with a corresponding micropore ratio of 36 and 26%, respectively. Both aerogels showed outstanding adsorption capacity, exceeding the reported performance of other carbons and Ag-doped materials. Owing to its basic nature, the RMF-GO carbon aerogel showed higher I\u2212 capacity, up to 97 mg\/g, than the acidic RF_ac, which reached a capacity of 82 mg\/g. The surface chemistry of the aerogels also played a distinct role in the removal. In terms of kinetics, RF_ac removed 60% of the iodide ions and RMF-GO 30% within 8 h. The removal kinetics was of the first order, with a half-life of 1.94 and 1.70 h, respectively.<\/jats:p>","DOI":"10.3390\/ma15196885","type":"journal-article","created":{"date-parts":[[2022,10,9]],"date-time":"2022-10-09T01:43:11Z","timestamp":1665279791000},"page":"6885","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Iodide Removal by Resorcinol-Formaldehyde Carbon Aerogels"],"prefix":"10.3390","volume":"15","author":[{"given":"Andrea","family":"Dom\u00e1n","sequence":"first","affiliation":[{"name":"Surface Chemistry Group, Department of Physical Chemistry and Materials Science, Faculty of Chemical Technology and Biotechnology, Budapest University of Technology and Economics, M\u0171egyetem rkp. 3, 1111 Budapest, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bekassyl","family":"Battalgazy","sequence":"additional","affiliation":[{"name":"Environmental Science & Technology Group (ESTg), Department of Chemical & Materials Engineering, School of Engineering, Nazarbayev University, Qabanbay Batyr Ave 53, Nur-Sultan 010000, Kazakhstan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"G\u00e1bor","family":"Dobos","sequence":"additional","affiliation":[{"name":"Surface Physics Laboratory, Department of Atomic Physics, Budapest University of Technology and Economics, M\u0171egyetem rkp. 3, 1111 Budapest, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"G\u00e1bor","family":"Kiss","sequence":"additional","affiliation":[{"name":"Surface Physics Laboratory, Department of Atomic Physics, Budapest University of Technology and Economics, M\u0171egyetem rkp. 3, 1111 Budapest, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6150-7580","authenticated-orcid":false,"given":"Zhandos","family":"Tauanov","sequence":"additional","affiliation":[{"name":"Faculty of Chemistry and Chemical Technology, al-Farabi Kazakh National University, 71 al-Farabi Ave., Almaty 050040, Kazakhstan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4499-3983","authenticated-orcid":false,"given":"Krisztina","family":"L\u00e1szl\u00f3","sequence":"additional","affiliation":[{"name":"Surface Chemistry Group, Department of Physical Chemistry and Materials Science, Faculty of Chemical Technology and Biotechnology, Budapest University of Technology and Economics, M\u0171egyetem rkp. 3, 1111 Budapest, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8154-5656","authenticated-orcid":false,"given":"Antonis A.","family":"Zorpas","sequence":"additional","affiliation":[{"name":"Laboratory of Chemical Engineering and Engineering Sustainability, Faculty of Pure and Applied Science, Open University of Cyprus, Giannou Kranidioti 33, Latsia, Nicosia 2220, Cyprus"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0195-0417","authenticated-orcid":false,"given":"Vassilis J.","family":"Inglezakis","sequence":"additional","affiliation":[{"name":"Chemical and Process Engineering Department, University of Strathclyde, 75 Montrose Street, Glasgow G1 1XJ, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,10,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"301","DOI":"10.1038\/nature06599","article-title":"Science and Technology for Water Purification in the Coming Decades","volume":"452","author":"Shannon","year":"2008","journal-title":"Nature"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"282","DOI":"10.1016\/j.apgeochem.2015.09.013","article-title":"Iodine and Human Health, the Role of Environmental Geochemistry and Diet, a Review","volume":"63","author":"Fuge","year":"2015","journal-title":"Appl.
