Other claims from this paper (5)
- Method / resource Even in a cryostat at 12 K, Fe III can photoreduce to Fe II within 0.5-1 min during X-ray absorption analysis.
- Method / resource Photoreduction of Fe III was considerably higher for aqueous standard compounds than for hydrated plant-root tissues.
- Intervention effect Freeze-dried samples in the cryostat markedly reduced the magnitude of Fe III photoreduction.
- Observation Comparatively small differences were observed between spectra of hydrated and freeze-dried Fe II compounds.
- Recommendation The authors recommend that all XAS studies include a preliminary experiment to determine whether beam damage is occurring.
