| Outline of Final Research Achievements |
Chemical correlation between two kinds of elements in materials were tried to evaluate by update of the imaging XAFS technique. In the analysis, imaging XAFS spectra of two different elements in soil, adsorbent and borosilicate glass were obtained and correlation between them was investigated. It can be seen that more cesium adheres to the soil containing trivalent iron rather than divalent iron. It is concluded that chemical state of rhodium in the borosilicate glass is controlled by distribution of ruthenium element. We confirmed extension of the imaging XAFS technique tried in the present work was effective for the chemical correlation analysis.
