The magnetic MnFe<jats:sub>2<\/jats:sub>O<jats:sub>4<\/jats:sub> nanoparticles were employed in a fixed bed experimental system to investigate the adsorption capacity of Hg<jats:sup>0<\/jats:sup> from air. The MnFe<jats:sub>2<\/jats:sub>O<jats:sub>4<\/jats:sub> nanoparticles exhibited the large adsorption performance on Hg<jats:sup>0<\/jats:sup> with the adsorption capacity of 16.27 \u03bcg\/g at the adsorption temperature of 50 \u00b0C with the space velocity of 4.8\u00d710<jats:sup>4<\/jats:sup> h<jats:sup>-1<\/jats:sup>. The VSM and EDS results illustrated that the prepared MnFe<jats:sub>2<\/jats:sub>O<jats:sub>4<\/jats:sub> nanoparticles were stable before and after adsorption and successfully adsorbed Hg<jats:sup>0<\/jats:sup>. The TG curves demonstrated that the mercury compound formed after adsorption was HgO, and both physical and chemical adsorption processes were observed. Magnetic MnFe<jats:sub>2<\/jats:sub>O<jats:sub>4<\/jats:sub> nanoparticles revealed excellent adsorbance of Hg<jats:sup>0<\/jats:sup> in air, which suggested that MnFe<jats:sub>2<\/jats:sub>O<jats:sub>4<\/jats:sub> nanoparticles be promising for the removal of Hg<jats:sup>0<\/jats:sup>.<\/jats:p>","DOI":"10.1371\/journal.pone.0304333","type":"journal-article","created":{"date-parts":[[2024,6,14]],"date-time":"2024-06-14T17:23:07Z","timestamp":1718385787000},"page":"e0304333","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":1,"title":["Adsorption of magnetic manganese ferrites to simulated monomeric mercury in flue gases"],"prefix":"10.1371","volume":"19","author":[{"given":"Lei","family":"Sun","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiajun","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhou","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7231-4357","authenticated-orcid":true,"given":"Min","family":"Liu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"340","published-online":{"date-parts":[[2024,6,14]]},"reference":[{"key":"pone.0304333.ref001","doi-asserted-by":"crossref","first-page":"121855","DOI":"10.1016\/j.ica.2023.121855","article-title":"Amino acid-induced exfoliation of MoS2 nanosheets through hydrothermal method for the removal of mercury","volume":"561","author":"R Pirarath","year":"2024","journal-title":"Inorg.
