Abstract
The solubilities of lead oxide (PbO) and copper oxide (CuO) in subcritical and supercritical water were measured at temperatures from 250°C to 500°C and pressures from 26 MPa to 34 MPa, in a flow-type apparatus. The solubility of lead oxide varied from 351 μmol/kg H2O at 424.9°C and 25.9 MPa to 4406 μmol/kg H2O at 350.3°C and 30.2 MPa. The solubility of copper of oxide varied from 1.3 μmol/kg H2O at 449.8°C and 28.0 MPa to 8.0 μmol/kg H2O at 324.9°C and 28.1 MPa. A hydration reaction model was applied to correlated the data.
