The objective of this study was to examine the homogeneous and heterogeneous reduction of Cr(VI) by dissolved Fe(II) and Fe(II)-containing minerals under conditions thought to be indicative of HLW fluids (high pH, high ionic strength and high temperature). Many investigators have reported the homogeneous reduction of Cr(VI) by dissolved FE(ii), but less information is available for Ph values > 8. The first part of this effort evaluated the ability of dissolved Fe(II) to reduce dissolved Cr(VI) in hyperalkaline solutions
