X-ray diffraction, energy\u2013dispersive analysis, scanning electron microscopy, vibrational magnetic spectroscopy, and m\u00f6ssbauer spectroscopy were used as research methods. It is shown that an increase in the dopant concentration leads to the transformation of the shape of nanoparticles from spherical to cubic and rhombic, followed by an increase in the size of the nanoparticles. The spherical shape of the nanoparticles is characteristic of a structure consisting of a mixture of two phases of hematite (Fe2O3) and cerium oxide CeO2. The cubic shape of nanoparticles is typical for spinel-type FeNbO4 structures, the phase contribution of which increases with increasing dopant concentration. It is shown that doping leads not only to a decrease in the concentration of manganese in model solutions, but also to an increase in the efficiency of adsorption from 11% to 75%.<\/jats:p>","DOI":"10.3390\/s20174851","type":"journal-article","created":{"date-parts":[[2020,8,27]],"date-time":"2020-08-27T08:05:18Z","timestamp":1598515518000},"page":"4851","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":296,"title":["Evaluation of the Efficiency of Detection and Capture of Manganese in Aqueous Solutions of FeCeOx Nanocomposites Doped with Nb2O5"],"prefix":"10.3390","volume":"20","author":[{"given":"Artem","family":"Kozlovskiy","sequence":"first","affiliation":[{"name":"Engineering Profile Laboratory, L.N.Gumilyov Eurasian National University, Satpaev str. 5, Nur-Sultan 010008, Kazakhstan"},{"name":"Laboratory of Solid State Physics, The Institute of Nuclear Physics, Ibrag and ov str. 1, Almaty 050032, Kazakhstan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kamila","family":"Egizbek","sequence":"additional","affiliation":[{"name":"Engineering Profile Laboratory, L.N.Gumilyov Eurasian National University, Satpaev str. 5, Nur-Sultan 010008, Kazakhstan"},{"name":"Laboratory of Solid State Physics, The Institute of Nuclear Physics, Ibrag and ov str. 1, Almaty 050032, Kazakhstan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2992-1375","authenticated-orcid":false,"given":"Maxim V.","family":"Zdorovets","sequence":"additional","affiliation":[{"name":"Engineering Profile Laboratory, L.N.Gumilyov Eurasian National University, Satpaev str. 5, Nur-Sultan 010008, Kazakhstan"},{"name":"Laboratory of Solid State Physics, The Institute of Nuclear Physics, Ibrag and ov str. 1, Almaty 050032, Kazakhstan"},{"name":"Department of Intelligent Information Technologies, Ural Federal University, Mira str. 19, 620002 Ekaterinburg, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Milana","family":"Ibragimova","sequence":"additional","affiliation":[{"name":"Engineering Profile Laboratory, L.N.Gumilyov Eurasian National University, Satpaev str. 5, Nur-Sultan 010008, Kazakhstan"},{"name":"Laboratory of Solid State Physics, The Institute of Nuclear Physics, Ibrag and ov str. 1, Almaty 050032, Kazakhstan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5429-820X","authenticated-orcid":false,"given":"Alena","family":"Shumskaya","sequence":"additional","affiliation":[{"name":"Optical Anisotropic Films Laboratory, Institute of Chemistry of New Materials of the National Academy of Sciences of Belarus, 22007 Minsk, Belarus"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexandr A.","family":"Rogachev","sequence":"additional","affiliation":[{"name":"Optical Anisotropic Films Laboratory, Institute of Chemistry of New Materials of the National Academy of Sciences of Belarus, 22007 Minsk, Belarus"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhanna V.","family":"Ignatovich","sequence":"additional","affiliation":[{"name":"Optical Anisotropic Films Laboratory, Institute of Chemistry of New Materials of the National Academy of Sciences of Belarus, 22007 Minsk, Belarus"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kayrat","family":"Kadyrzhanov","sequence":"additional","affiliation":[{"name":"Engineering Profile Laboratory, L.N.Gumilyov Eurasian National University, Satpaev str. 5, Nur-Sultan 010008, Kazakhstan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,8,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"109","DOI":"10.1016\/j.jes.2020.04.033","article-title":"Ce-based catalysts used in advanced oxidation processes for organic wastewater treatment: A review","volume":"96","author":"Niu","year":"2020","journal-title":"J.
