Abstract

The oxidation state and local environment of Fe atoms in a series of vitrified lead-rich industrial wastes, as a function of the ash content, is studied using EXAFS and NEXAFS measurements at the Fe-K edge. The Fe-K EXAFS results reveal that the Fe–O distance and the coordination number in the 1st nearest neighbour shell decrease with increasing ash content in the vitrified product. Information on the iron's valence state and the role of Pb2+ ions in the glass matrix is drawn from the characteristics of the pre-edge features and the position of the absorption edge in the NEXAFS spectra.
