The non-destructive x-ray absorption near-edge structure (XANES) method was applied to the quantitative determination of chromium and arsenic species in coal Γy ash. In order to study the chemical state changes caused by deposition and sedimentation of the particles, land Γll and river sediment samp

XANES spectra of Co complexes have been measured in solid and solution. The spectra in aqueous solutions were found to remain unchanged at different concentrations, while they were found to differ from those in crystals. These findings suggest that the spectral change does not originate from a long-
L edge absorption spectra of PdClz have been obtained with synchrotron radiation. These results arc compared with those of Pd metal. It is found that their near edge structure can be understood qualitatively on the basis of dipole transition and the conventional description of bonding in these syste
