Effect of temperature on sodium oxalate solubility
- Savannah River Site (SRS), Aiken, SC (United States)
The solubility of sodium oxalate in basic solution at 20 deg C is strongly dependent on total sodium ion concentration. Because of the limited solubility in solutions with high sodium concentration, solid sodium oxalate could recycle to the main sludge slurry stream in the DWPF with solids from gravity settling and filtration if the [C2O4=] exceeds the solubility limit. Because process strams in the DWPF will be at a minimum of 38 deg C, tests have been completed to establish how oxalate solubility changes as the temperature is increased for a series of solutions representing the expected range of [Na+] in the DWPF.
