Response to Comment on 'Direct Observation of Tetrahedrally Coordinated Fe(Ⅲ) in Ferrihydrite'

摘要

We appreciate the concern that has been expressed by Hocking et al. regarding the use of linear combination fitting to extract information from the L-edge spectra of ferrihydrite. We share these concerns, which was the reason that we only make a rough estimate on the amount of tetrahedrally coordinated Fe(Ⅲ) in ferrihydrite.1 The role of effective nuclear charge, bond covalency, and potential errors in linear combination fitting put forth by Hocking et al.
