The swelling equilibrium for the system water-ethylene glycol-crosslinked PVA at various temperatures were experimentally investigated.A liquid-membrane swelling equilibrium model was developed on the basis of modified UNIQUAC equation and Flory-Huggins thermodynamics and good agreement between the derived equation predictions and the experimental values for the preferential sorption of water-ethylene glycol mixture in the crosslinked PVA membrane was obtained.
