Title: Technetium-99 MAS NMR Spectroscopy of a Cationic Framework Material that Traps TcO 4 - Ions

Abstract

No chance for technetium: 99Tc magic-angle spinning (MAS) NMR spectra show that TcO4- ions, which are generated by nuclear fission and can contaminate the environment, can be trapped within the channels and cavities of a cationic framework material (see picture). These spectra are among the first 99Tc MAS NMR spectra reported to date, and show that the TcO4- ions can be efficiently removed from simulated nuclear waste solutions.
