Molecularly imprinted porous polysulfone particles for the binding and recognition of bisphenol A Bisphenol A (BPA)-imprinted polysulfone (PSf) particles for the binding and recognition of BPA were prepared by means of a phase inversion technique. The porosity of the PSf particles was about 70%. Binding and recognition of BPA for the particles were investigated; the binding amounts increased ver Desalination 245 (2009)
Absorption of nitrogen dioxide by PVDF hollow fiber membranes in a G–L contactor Microporous asymmetric PVDF hollow fiber membranes were prepared from commercially available polyvinylidenefluoride and N,N-dimethylacetamide (DMAc) by the dry-jet wet phase inversion process. Lithium chloride and water were used as additives. Mean pores size and effective surface porosity were eval Desalination 243 (2009)
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 for preparation of flat sheet membranes. Effects of CA Desalination 243 (2009)
Evaluation of self-made nanoporous polyethersulfone membranes, relative to commercial nanofiltration membranes The phase inversion technique was used in this study to prepare polyethersulfone membranes. After optimizing the synthesis factors, like the relative air humidity, the concentration of the polymer and the used solvent, nanoporous membranes were obtained. Characterization of these membranes indicated Desalination 200 (2006)
Preparation and characterisation of novel PEEKWC capsules by phase inversion technique Capsules of PEEKWC are prepared using a membrane process combined with phase inversion technique. Polymeric droplets were prepared using a mono-pore film in polyethylene with pore diameter ranging from 300 to 1000 mm. The morphology, porosity and shell thickness of the made capsules are modified cha Desalination 199 (2006)
Preparation and characterization of polyacrylonitrile-based membranes: Effects of internal coagulant on poly(acrylonitrileco-maleic acid) ultrafiltration hollow fiber membranes Ultrafiltration hollow-fiber membranes (UHFMs) of poly(acrylonitrile-co-maleic acid) (PANCMA) were prepared by a dry-wet phase inversion process. The morphologies of inner surface and cross section for these hollow fibers were inspected with scanning electron microscopy. It was found that, by increa Desalination 160 (2004)
Trade-off between thermodynamic enhancement and kinetic hindrance during phase inversion in the preparation of polysulfone membranes Polysulfone membranes were prepared via the diffusion-induced phase inversion process from casting solutions consisting of polysulfone, dimethyformamide, and polyvinyl pyrrolidone as a polymeric additive. The effect of PVP added in casting solutions was analyzed by measuring the prepared membranes’ Desalination 159 (2003)
Preparation of polyacrylonitrile ultrafiltration membranes for wastewater treatment The preparation conditions of a polyacrylonitrile (PAN) ultrafiltration membrane for wastewater treatment was investigated. The PAN membranes were prepared by the phase-inversion process in a water gelation bath using casting solutions of varying compositions of PAN/polyvinylpyrolidone (PVP)/N,N-dim Desalination 144 (2002)
