Fe K-edge XANES and EXAFS of the x-ray absorption spectra of FeCl3 aqueous solutions
- 1. Tokyo Univ. (Japan). Faculty of Science
Description
The Fe K-edge spectra were measured on FeCl3 aqueous solutions by use of synchrotron radiation to reveal the solute structure from the analysis of Fe K-edge EXAFS and XANES. It is concluded that the solute exists mainly as [Fe(H2O)6]3+ but partially as [FeCl(H2O)5]3+ at FeCl3 concentration of 0.1 - 1 mol dm-3, and it exsits mainly as [FeCl2(H2O)4]+ at the concentration of 3 - 4 mol dm-3. In the diliquescent product of FeCl3, about a half of the solute is in the state of [FeCl4]- and the remaining half is likely to be in the state of [FeCl2(H2O)4]+. No indication was found for the dimer formation of FeCl3 even in the deliquescent product. (author)
