host of hexavalent chromium [Cr (VI)] in cementitious and alkaline solids such as chromium
ore processing residue (COPR). Leaching from COPR often results in Cr (VI) contamination
of soil and groundwater. Although Cr-hydrogarnet has been synthesized and characterized
previously, its solubility product (K sp) is poorly constrained. Accurate determination of this
thermodynamic parameter is critical to quantify the extent of Cr (VI) dissolution from COPR in …
