Normalized As XANES spectra. The spectra are vertically offset for clarity. Sediment samples from duplicate microcosms were combined before analysis, dashed lines – Day 12.5, solid lines – Day 38.0. Reference spectra are included for comparison. Arsenic XANES of magnetite structural As(V) was obtained from Saalfield and Bostick (2009), showing broad peaks (b.p.) at 11883 eV and 11895 eV.
