Abstract
Swelling equilibrium experiments for the system water-ethylene glycol- crosslinked PVA membrane at various temperatures were investigated. A liquid-membrane swelling equilibrium model was developed on the basis of a modified UNIQUAC equation and Flory-Huggins thermodynamics and go od agreement between the derived equation predictions and the experime ntal values for the preferential sorption of water-ethylene glycol mix tures in the crosslinked PVA membrane was obtained.
