Separation Efficiency of Epoxified-Polyethersulfone Blend Membrane for Chromium Removal
A microporous bisphenol A diglycidyl ether (DGEBA) epoxified-polyethersulfone (PES) blend membrane (EPES membrane) was prepared through dry-wet phase inversion. This study attempts to correlate the changes in membrane physical and chemical properties when the EPES membranes were exposed to different durations of dry-phase inversion, towards the separation efficiency of carcinogen chromium (VI)....
متن کاملPreparation and Characterization of Poly (vinyl alcohol) Membrane for Pervaporation Separation of Water-Organic Mixtures
Poly (vinyl alcohol) membranes were prepared by in-situ crosslinking of poly (vinyl alcohol) with glutaraldehyde as a crosslinking agent and hydrochloric acid as catalyst and the membranes were used to separate mixtures of IPA and water. Effects of feed composition, operating temperature, vacuum pressure and Reynolds number on permeation performance of the membranes were evaluated. The results ...
متن کاملA Predictive Model for the Selective Separation of Aromatic/Non Aromatic Hydrocarbon Mixtures by Pervaporation Using Dense Homogenous Polymer Membranes
Separation of aromatic/non-aromatic mixtures by membrane based pervaportion process is usually analyzed by the solution-diffusion model which assumes that a permeating component is first dissolved in the membrane and then diffuses through the membrane due to its driving force. Therefore, the separate evaluation of sorption equilibria is necessary in order to determine the controlling step in ov...

متن کاملPervaporation of alcohol-toluene mixtures through polymer blend membranes of poly ( acrylic acid) and poly (vinyl alcohol)
Homogeneous membranes were prepared by blending poly (acrylic acid) with poly (vinyl alcohol). These blend membranes were evaluated for the selective separation of alcohols from toluene by pervaporation. The flux and selectivity of the membranes were determined both as a function of the blend composition and of the feed mixture composition. The results showed that a polymer blending method coul...
