UNIQUAC and UNIQUAC-HB models for the sorption behavior of ethanol/water mixtures in a cross-linked polydimethylsiloxane membrane

▸ Ethanol/water sorption behaviors are investigated in PDMS film at 298 K. ▸ UNIQUAC model gives fast estimates of partial component uptakes. ▸ UNIQUAC-HB model predicts the synergistic effect of ethanol/water mixtures in PDMS.
