In this research, magnetically modified biochar obtained from poor-quality wheat with two distinct FexOy contents was studied as a sorbent for the elimination of beryllium from an aqueous solution. The determined elimination efficiency was higher than 80% in both prepared composites, and the presence of FexOy did not affect the sorption properties. The experimental qmax values were determined to be 1.44 mg\/g for original biochar and biochar with lower content of iron and 1.45 mg\/g for the biochar with higher iron content. The optimum pH values favorable for sorption were determined to be 6. After the sorption procedure, the sorbent was still magnetically active enough to be removed from the solution by a magnet. Using magnetically modified sorbents proved to be an easy to apply, low-cost, and effective technique.<\/jats:p>","DOI":"10.3390\/ma14216610","type":"journal-article","created":{"date-parts":[[2021,11,3]],"date-time":"2021-11-03T21:57:49Z","timestamp":1635976669000},"page":"6610","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Magnetically Modified Biosorbent for Rapid Beryllium Elimination from the Aqueous Environment"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0689-8627","authenticated-orcid":false,"given":"Michaela","family":"Tokar\u010d\u00edkov\u00e1","sequence":"first","affiliation":[{"name":"Nanotechnology Centre, Energy and Environmental Technology Centre, V\u0160B-Technical University of Ostrava, 708 33 Ostrava-Poruba, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9644-0611","authenticated-orcid":false,"given":"Old\u0159ich","family":"Motyka","sequence":"additional","affiliation":[{"name":"Nanotechnology Centre, Energy and Environmental Technology Centre, V\u0160B-Technical University of Ostrava, 708 33 Ostrava-Poruba, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6272-2744","authenticated-orcid":false,"given":"Pavl\u00edna","family":"Peikertov\u00e1","sequence":"additional","affiliation":[{"name":"Nanotechnology Centre, Energy and Environmental Technology Centre, V\u0160B-Technical University of Ostrava, 708 33 Ostrava-Poruba, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roman","family":"Gabor","sequence":"additional","affiliation":[{"name":"Nanotechnology Centre, Energy and Environmental Technology Centre, V\u0160B-Technical University of Ostrava, 708 33 Ostrava-Poruba, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jana","family":"Seidlerov\u00e1","sequence":"additional","affiliation":[{"name":"Nanotechnology Centre, Energy and Environmental Technology Centre, V\u0160B-Technical University of Ostrava, 708 33 Ostrava-Poruba, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,11,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"108","DOI":"10.1016\/j.resmic.2005.06.005","article-title":"Cytotoxicity and bioaccumulation of heavy metals by ciliated protozoa isolated from urban wastewater treatment plants","volume":"157","author":"Borniquel","year":"2006","journal-title":"Res.
