In a recent article (Espinosa et al 2012 Meas. Sci. Technol. 23 015602), the authors have presented a method for the quantification of magnetite (Fe3O4) and maghemite (γ -Fe2O3) from x-ray absorption near edge spectroscopy at the Fe K-edge in the fluorescence mode. In this comment, I point out that the study was erroneously conducted in hematite (α-Fe2O3) instead of maghemite. Accordingly, the authors’ conclusions need to be revised.

Abstract
In a recent article (Espinosa et al 2012 Meas. Sci. Technol. 23 015602), the authors have presented a method for the quantification of magnetite (Fe3O4) and maghemite (γ -Fe2O3) from x-ray absorption near edge spectroscopy at the Fe K-edge in the fluorescence mode. In this comment, I point out that the study was erroneously conducted in hematite (α-Fe2O3) instead of maghemite. Accordingly, the authors’ conclusions need to be revised.File in questo prodotto:
