(a) As K-edge XANES spectra, (b) LCF results of XANES spectra, (c) k3-weighted EXAFS spectra (solid lines) with the fitting results (dotted lines) and (d) the corresponding FTs (solid lines) with the fitting results (dotted lines) for the unaerated As(III)- and As(V)-reacted FeS at pH 5, 7 and 9 using a He flow sample chamber. The samples that did not undergo redox transformation are represented by single spectra, and those undergoing the photo-reduction are represented by a series of successive scans. The beam exposure time was about 37 min per scan in a series of multiple scans.
