Figure 1
Dataset of 99 Cu K-edge XANES spectra collected on a thin section from a paddy soil. (a) Gray-scale micro X-ray fluorescence (XRF) map in negative contrast showing the inhomogeneous distribution of Cu which occurs in about six different organic and inorganic forms. Color maps are shown in Fig. S1 of the supporting information. Image size: 1.57 mm (H) × 1.04 mm (V); beam size and pixel size: 3.0 µm (H) × 3.0 µm (V). (b) Micro-XANES spectra collected at 99 spots having different compositions as seen from the XRF map. Data were recorded on beamline 10.3.2 at the ALS (Berkeley). |
