In situ MONITORING OF SYNCHROTRON X-RAY-INDUCED RADIOLYSIS EFFECTS ON CHROMIUM SPECIES USING X-RAY ABSORPTION SPECTROSCOPY
Abstract
Synchrotron X-ray radiolysis-induced redox in a chromium aqueous solution was monitored using in situ X-ray absorption spectroscopy. The radiolysis in the fluid sample within a specifically designed hydrothermal diamond anvil cell caused the oxidation of Cr(III) to Cr(VI) upon heating from room temperature to 400oC, and reduction of Cr(VI) to Cr(III) at 500oC. The two fitted components of the pre-edge features of the Cr K-edge spectra were used to identify the presence of Cr(VI) in the solution.
