A Review on Mixed Matrix Membranes for Solvent Dehydration and Recovery Process

open access: yesMembranes, 2021
Solvent separation and dehydration are important operations for industries and laboratories. Processes such as distillation and extraction are not always effective and are energy-consuming.

Preferential sorption versus preferential permeability in pervaporation [PDF]

open access: yes, 1985
Transport of liquids by pervaporation takes place by a solution—diffusion mechanism. In order to investigate the “solution part” of this transport model, preferential sorption has been compared with preferential permeability.

Selection of elastomeric membranes for the removal of volatile organics from water [PDF]

open access: yes, 1993
A wide range of homogeneous elastomeric membranes has been prepared using dicumylperoxide as a general cross-linking agent. The membranes have been used for both equilibrium sorption measurements and steady-state pervaporation experiments to study ...
