摘要

The uranium carbonate andersonite 6H_2O was synthesized and identified with classical analytical and spectroscopic methods.The classical methods applied were powder X-ray diffraction(XRD),nitric acid digestion,and scanning electron microcopy combined with energy-dispersive spectroscopy(SEM/EDS).To characterize andersonite spectroscopically,time-resolved laser-induced fluorescence spectroscopy(TRLFS),X-ray photo-electron spectroscopy(XPS),and Fourier transform infrared spectroscopy(FT-IR)were used.Natural and synthetic andersonite samples were characterized with the nondestructive TRLFS by six fluorescence emission bands at 470.6,486.1,505.4,526.7,549.6,and 573.9 nm.
