Chromium Speciation in the Size

Jul 18, 2018The chromate ore process residues (COPR) polluted soil was physically separated into coarse sand (2.000–0.425 mm), fine sand (0.425–0.053 mm) and silt to clay ( 0.053 mm) fractions. The Cr speciation was characterized by synchrotron based micro X-ray fluorescence ( -XRF) and micro X-ray absorption near-edge spectra ( -XANES).
