20.500.12556/RUL-169966 Selective separations of Am(III)/Eu(III) using heterocyclic bistriazinyl phosphonate grafted zirconia and titania solid phase extractants Surface functionalization of metal oxides with phosphonic acid monolayers by covalent bonding enables the generation of robust hybrid materials with enhanced separation properties. Mesoporous crystalline zirconia and titania serve as applicable inorganic supports with high thermal stability and resistance to oxidation, acidity and radiolysis. We have fabricated selective solid phase extractants that efficiently separate americium and europium from each other, via straightforward grafting of the zirconia and titania surfaces with N- and S-donor complexing agents, namely 2,6-bis-triazolyl-pyridine derivatives. Separation factors (Am/Eu) up to 13 were obtained in binary solution at pH 2 and preference for Am over Eu was observed even in Eu excess solution. These stable hybrid materials can be utilized for separation purposes without substantial degradation, providing advantageous reusability and a greener option in comparison to commonly used solvent extraction methods. americium europium separation recycling trapping americij evropij ločba recikliranje zajetje true false true Angleški jezik Slovenski jezik Članek v reviji 2025-06-27 09:23:01 2025-06-27 09:23:02 2025-06-28 04:07:59 0000-00-00 00:00:00 2025 0 0 Str. 279-291 iss. 1 Vol. 2 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 546.661:546.798.23 2755-3701 10.1039/D4LF00277F 217316611 RAZ_Hiltunen_O-M._2025.pdf RAZ_Hiltunen_O-M._2025.pdf 1 9EAC8891CFFBC7F7685F648DD4505781 3b46d96507e4407c42d954e559b0d60bff5a6d703082f6f4513ff1429b999e30 000d1f8e-5326-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=211825 https://pubs.rsc.org/en/Content/ArticleLanding/2025/LF/D4LF00277F 1 b0555099-5325-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=211824 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
