Water Desalination Using Polyelectrolyte Hydrogel: Gibbs Ensemble Modeling
Polyelectrolyte hydrogels can absorb a large amount of water across an osmotic membrane as a result of their swelling pressure.On the other hand, the insoluble cross-linked hydrogel network enables dewatering under the influence of external (thermal and/or mechanical) stimuli.Moreover, from a thermodynamic perspective, a polyelectrolyte hydrogel is
