99 Tc魔角旋转（MAS）NMR光谱显示，TcO 4-离子，由核裂变产生，可以污染环境，可以被捕获在阳离子骨架材料的通道和空腔内（见图）。这些光谱是迄今为止报道的第一批99 Tc MAS NMR光谱，并表明TcO 4-离子可以有效地从模拟核废料溶液中去除。
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.
