Analysis of Soft-x-ray Absorption Spectra Measured by a Total-fluorescence X-ray-yield Mode Using Electronic State Calculations: Structure Analysis of Powder and Aqueous Solution of Sodium Aluminate

Document Type



X-ray absorption spectra near Na and Al K-edges of powder and aqueous solution of sodium aluminate have been measured with a total fluorescence yield mode using our experiment setup under in-situ conditions. The coordination structures to Al in powder and aqueous solution are found from the spectral analysis by means of electronic state calculations for the corresponding structure models. The proportion of some complex species in powder and aqueous solution can be also estimated.
