The EXAFS measurement of simulated waste glass prepared under several heating conditions were performed to clarify redox state of Ru, Rh and Pd elements. The EXAFS functions were fitted by linear combination of standard functions of pure metal and its oxide. A ratio of metallic and oxide components in the simulated glass was obtained from the fitting analysis. We proposed we could evaluate redox state in the process of glass melters.
