RISPolysulfone/Brij-58 blend nanofiltration membranes: preparation, morphology and performance
In present research, novel asymmetric polysulfone (PSF)membraneswith high hydrophilicity and noticeable rejection of arsenic, as one of the major environmental problems, were prepared from PSF/Brij-58/NMP (1-methyl-2-pyrrolidone) ...
preparation and application of nano emulsion in the last decade(2000_2010)
(low energy emulsification). High energy emulsification consists of high pressure homogenization (HPH), ultrasonication and microfluidization and low energy emulsification consists of phase inversion temperature (PIT), phase inversion composition (PIC...
Enhanced modification technique for polyacrylonitrile UF membranes by direct hydrolysis in the immersion bath
Conventional hydrolysis modification of polyacrylonitrile (PAN) membranes is usually carried out in a post-treatment step during which hydrophilic groups are created on the membrane surface. In this article, however, direct ...
Study of gas separation properties of ethylene vinyl acetate (EVA) copolymer membranes prepared via phase inversion method
The gas separation properties of Ethylene Vinyl Acetate (EVA) membranes containing 18 and 28 wt% of vinyl acetate were investigated in this study. The effects of membrane preparation conditions, such as thermal and thermal/wet phase inversion...
Preparation and characterization of Polycaprolactone/Extra virgin olive oil membranes by immersion precipitation for tissue engineering application
In this study, polycaprolactone -PCL- membranes were prepared through immersion precipitation using a mixture of two solvents -tetrahydrofuran -THF- and dimethyl formamide -DMF--, and modified by incorporating extra virgin ...
Effect of preparation variables on morphology and pure water permeation flux through asymmetric cellulose acetate membranes
In this study, cellulose acetate (CA) ultrafiltration (UF) membranes were prepared using the phase inversion method. Effects of CA and polyethylene glycol (PEG) concentrations in the casting solution and
coagulation bath temperature (CBT...
Polyacrylonitrile (PAN)/IGEPAL blend asymmetric membranes: preparation, morphology, and performance
Polyacrylonitrile (PAN) membranes are widely applied in many chemical engineering fields. In this research,
novel asymmetric PAN membranes with high hydrophilicity and permeability were prepared from a PAN/polyoxyethylene ...
Effect of production conditions on morphology and permeability of asymmetric cellulose acetate membranes
Membranes are widely used in wastewater treatment. In this study, cellulose acetate (CA) (Mw = 52,000) was mixed with polyethylene glycol (PEG) (Mw = 400) as an additive in N-methyl-2-pyrrolidone as a solvent. The phase inversion method was used...
A Novel Cellulose Acetate (CA) Membrane Using TiO2 Nanoparticles: Preparation, Characterization and Permeation Study
CA/TiO2 hybrid membranes were prepared via phase inversion by dispersing TiO2 nanopaticles in the CA casting solutions. TiO2 nanoparticles, which were synthesized by the sonochemical method, were added into the casting solution in different...
