Amine-modified maleic anhydride containing terpolymers for the adsorption of uranyl ion in aqueous solutionsSimsek, SelcukYilmaz, ErsenBoztug, AliAdsorptionUranylPolymerAmineMaleic anhydride-styrene-methyl methacrylate (MA-S-MM) terpolymer was prepared. It was modified by ethylenediamine (EDA) and diethylenetriamine (DETA) in order to get cross-linked polymers bearing carboxyl and amine groups. Modified polymers used as an adsorbent for the removal of UO2 (2+) from water. The characterizations of structures of all the polymers were performed by Fourier transform infrared. The adsorptive features of adsorbents were then investigated for UO2 (2+) in view of dependency on ion concentration, pH, temperature and kinetics. Experimentally obtained isotherms were evaluated with reference to Langmuir, Freundlich and Dubinin-Radushkevich models. The maximum monolayer adsorption capacity for UO2 (2+) was found to be 1.59 and 2.43 mol kg(-1) for EDA-MA-S-MM and DETA-MA-S-MM, respectively. It can be said that the new modified polymers prepared in our laboratory have been suggested as new adsorbents for uranyl ions.SPRINGER2013-11Articlehttps://rdlopen.rawdatalibrary.net/r/munzur/4955https://doi.org/10.1007/s10967-013-2529-40236-5731enJOURNAL OF RADIOANALYTICAL AND NUCLEAR CHEMISTRYinfo:eu-repo/semantics/closedAccessinfo:eu-repo/semantics/articlehttps://munzur-rdlopen.rawdatalibrary.net/tr/items/munzur/4955
