o:4114 Analysis the surface of modified lignin based microspheres used for selenium adsorption by the sem-eds analytical method en Аbstract: This paper presents the results of the morphological and elemental analysis of the material tested for evaluation the adsorption of selenium (Se) from water, obtained applying the SEM-EDS method. The tested material was obtained from a natural polymer - kraft lignin by the process of suspension copolymerization and additional modification with nanoparticles of iron oxide in the form of magnetite, called the A-LMS Fe3O4. According to the obtained morphological data, the A-LMS Fe3O4 material is highly porous, and the particles are irregularly spherical. The elemental analysis of material after the process of Se adsorption from water, using an EDS detector, detected the characteristic signals for Se. Keywords: selenium, SEM-EDS analysis, adsorption, magnetite. 91552100 134691081 1552100 978-86-7827-052-9 2024-03-05T14:21:13.183Z 44 no 46 Vesna Marjanović Institut za rudarstvo i metalurgiju Bor 77047049 0000-0001-8005-5244 2022 46 Radmila Marković Institut za rudarstvo i metalurgiju Bor 67811081 0000-0001-9754-1150 2022 46 Silvana Dimitrijević Institut za rudarstvo i metalurgiju Bor 25647975 0000-0003-1670-4275 2022 46 Zoran Stevanović Institut za rudarstvo i metalurgiju Bor 9619303 0000-0001-5317-6884 2022 application/pdf 442563 https://unilib.phaidrabg.rs/o:4114 no yes 1 70 669.776:549.731.1 92000004 71A03 Proceedings International October Conference on Mining and Metallurgy (53 ; 2022 ; Bor) 177 180 2022
