英文摘要 | The report describes results of experiments to synthesize and characterize uranium(VI)-silicates from solutions containing dissolved U(VI), Si, Na, and nitrate as a function of solution pH and Si:U ratio under ambient conditions. Solids characterization was accomplished by X-ray diffraction, attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR), and high-energy X-ray scattering (HEXS) analysis. The purpose was to develop a framework for describing the formation of U(VI)-silicate solids that might form in contaminated soils and sediments under oxidizing conditions in the presence of aqueous uranium, and are known to exist naturally in geologic uranium deposits. |
