No chance for technetium : 99 Tc magic‐angle spinning (MAS) NMR spectra show that TcO 4 − 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 99 Tc MAS NMR spectra reported to date, and show that the TcO 4 − ions can be efficiently removed from simulated nuclear waste solutions.
