Ethanol–Water Separation by Pervaporation through Substituted-Polyacetylene Membranes

Removal of Dilute Benzene in Water through Ionic Liquid/Poly(Vinyl Chloride) Membranes by Pervaporation

This paper focuses on the effects of the addition of an ionic liquid, 1-Allyl-3-butylimidazilium bis(trifluoromethane sulfonyl)imide ([ABIM]TFSI), which has a high affinity for benzene, into the poly(vinyl chloride) (PVC) membrane on the pervaporation characteristics of the removal of benzene from aqueous solutions of dilute benzene. When aqueous solutions of 100～500 ppm benzene were permeated ...

Pervaporation Membranes for Biobutanol Production

Because of the emerging scarcity of oil resources and the demand for environmental protection, as a typical biofuel, biobutanol produced by biomass fermentation is critical for the development of renewable energy. Pervaporation is considered to be an attractive separation technology for both the recovery of butanol from fermentation broth and the dehydration of butanol from low-water content so...

Spin-Charge Separation in Polyacetylene

Separation of aqueous salt solution by pervaporation through hybrid organic-inorganic membrane: effect of operating conditions

Hybrid polymer-inorganic membranes were prepared by crosslinking poly(vinyl alcohol) (PVA), maleic acid (MA) and silica via an aqueous sol-gel route. Membrane characterisation results revealed silica nanoparticles (<10 nm) were well dispersed in the polymer matrix and significantly reduced swelling of the membrane. The membranes were tested for pervaporation separation of aqueous salt solution ...
