Volume 4, Issue 4 , October 2019, , Pages 275-284

https://doi.org/10.22090/jwent.2019.04.002

Abstract
  In this study the efficiency of two different morphologies of polysulfone adsorptive membranes was examined for the humic acid removal from contaminated water. Adsorptive membranes with finger-like and sponge-like pore structures were prepared using modified montmorillonite with amino acid. Structure ...  Read More

Volume 4, Issue 4 , October 2019, , Pages 308-320

https://doi.org/10.22090/jwent.2019.04.005

Abstract
  In this work, KClO3, K2Cr2O7 and KMnO4, dissolved in sulfuric acid, were used to functionalize microporous Polysulfone (PSf) membranes; fabricated by phase inversion method. The optimum concentrations of oxidizing agent and sulfuric acid and membrane immersion times were determined. FTIR results revealed ...  Read More

Atefeh Tizchang; Yoones Jafarzadeh; Reza Yegani; Elham Shokri

Volume 4, Issue 3 , July 2019, , Pages 213-226

https://doi.org/10.22090/jwent.2019.03.004

Abstract
  In this study, polysulfone (PSf) nanocomposite membranes embedded with functionalized nanodiamond (ND) were prepared via Non-Solvent Induced Phase Separation (NIPS) method. ND nanoparticles were silanized by using the esterification reaction of hydrolyzed vinyltrimethoxysilane (VTS) in alcoholic solution ...  Read More

Volume 4, Issue 1 , January 2019, , Pages 1-16

https://doi.org/10.22090/jwent.2019.01.001

Abstract
  In this study, membranes were prepared by pristine and polyethylene glycol (PEG)-grafted ‎nanodiamond (ND) embedded in cellulose acetate (CA) as matrix polymer via non-solvent ‎induced phase separation method. The antifouling properties of the membranes were studied ‎during filtration of ...  Read More

Novel Adsorptive Mixed Matrix Membrane by Incorporating Modified Nanoclay with Amino Acid for Removal of Arsenic from Water

Elham Shokri; Reza Yegani

Volume 2, Issue 2 , April 2017, , Pages 88-95

https://doi.org/10.22090/jwent.2017.02.003

Abstract
  In this work, polysulfone (PSf) mixed matrix membranes were prepared by incorporating modified montmorillonite with lysine amino acid (MMT-Lys) for arsenic removal from water. Different tests including XRD, zeta potential, FE-SEM, contact angle, and pure water flux (PWF) were carried out to characterize ...  Read More
