Pervaporation separation of isopropanol-water mixtures using crosslinked chitosan membranes [PDF]

open access: yes, 2003
Chitosan membranes were prepared from local shrimp shells. Membranes were prepared as homogeneous (unmodified) and crosslinked chitosan. Chitosan membranes were modified via chemical crosslinking technique.

Pervaporation dehydration of bio-fuel (n-butanol) by dry thermal treatment membrane

open access: yesMaterials Research Express, 2020
In the present investigation, laboratory synthesized graphene oxide (GO) as a nano-filler was used in polyetherimide (PEI) flat-sheet membranes (PM). The PEI flat-sheet membrane was fabricated through a dry-thermal treatment (DTT) method.

Application of modified Maxwell-Stefan equation for separation of aqueous phenol by pervaporation

open access: yes, 2012
Pervaporation has the potential to be an alternative to the other traditional separation processes such as distillation, adsorption, reverse osmosis and extraction. This study investigates the separation of phenol from water using a polyurethane membrane

Characterization and Pervaporation Properties of Modified PU Membranes

open access: yesMATEC Web of Conferences, 2015
Pervaporation will have broad application prospects in the treatment of phenolic wastewater. Polyurethane (PU) membrane is promising but needs to be further modified. In this study, both β-CD and CNT were used to modify the PU membrane. The structure and
