Summary
| Description |
English: Tricolor (RGB) X-ray fluorescence image of the distribution of As (red), Fe (green), and Mn (blue) in coated quartz grains from a water treatment sand bed. This technology is used to produce potable water from raw water. Arsenic is associated with Fe oxides (speciated here as ferrihydrite), as shown by the yellow color of some layers. Their large variations in hue are indicative of varying As/Fe ratios. Some layers are green, due to the absence or low concentration of As. This fluorescence map was recorded on beamline 10.3.2 at the Advanced Light Source of the Lawrence Berkeley National Laboratory. Pixel size = 10 x 10 microns Adapted from Manceau et al. (Geochimica et Cosmochimic Acta, 2007, 71, 95-128) |
