Speciation of chromium in simulated soil samples using X-ray absorption spectroscopy and multivariate calibration

X-ray absorption near-edge structure (XANES) spectroscopy has been applied to the speciation of 24 simulated soil samples spiked with known concentrations (8–1015 ppm) of hexavalent and trivalent chromium. For XANES spectroscopy, multivariate calibration models, such as partial least-squares (PLS) r...
