文摘
- •
Polyelectrolyte complexes (PECs)/polyvinyl alcohol (PVA) membranes are pioneered for DD process of salts.
- •
PECs/PVA membranes have improved stability in water and salt solution.
- •
The dialysis coefficients of NaCl and NaAc are significantly higher than those of commercial membranes.
- •
PECs/PVA membranes can recover salt from NaCl/threonine mixture and NaAc waste residue solution.
