Composite microfiltration polyethersulfone membranes incorporating molecularly imprinted particles (MIPs) were developed for efficient and selective adsorption of 17β-estradiol from water.

Ultrafiltration using polyethersulfone-membranes was evaluated as an efficient and preferred method for purifying Cowpea Chlorotic Mottle Virus (CCMV). Cesium chloride (CsCl) ultracentrifugation and ultrafiltration protocols are described, and comparative UV-spectroscopic and electron micrograph results are presented. CCMV purified by ultrafiltration are shown to be equivalent to CCMV purified ...

Sulfonated polyethersulfone/sulfopropyl methacrylate membranes impregnated with the polysulfopropyl acrylate coated ZnO nanoparticles were developed using a non-solvent-induced phase separation recipe. The composite offered much-enhanced hydrophilicity and improved porosity, which are critical for excellent antifouling performance high permeate flux. By adding modified ZnO, it achieved maximum ...

Polyethersulfone (PES) is a common material used for ultrafiltration (UF) membranes, which has good chemical resistance, high mechanical properties, and wide temperature tolerances. The hydrophobic property of the PES membrane seriously limits its application. Cellulose fibrils are composed of micro-sized and nano-sized elements, which have high hydrophilicity, strength, and biodegradation. A c...

The adhesion of Escherichia coli, Pseudomonas putida and Acinetobacter calcoaceticus cells to MicrodynNadir ultrafiltration membranes of various chemical nature: PS100 (polysulfone), P005 (polyethersulfone), C100 (regenerated cellulose) was studied. It was shown that an adhesiveness of the microorganisms to the membranes essentially depends on hydrophobic/hydrophilic properties of both the cell...

Separation performances of micellar enhanced ultrafiltration process in Cr(III) and Cr(VI) removal has been evaluated. The neat as well as sulfonated and aminated derivatives of polyethersulfone were tested as the material for membrane preparation while hexadecylpyridine chloride and sodium dodecyl sulfate served as surfactant. It was shown that modified membranes can better reject both forms o...

We have ever developed micro dialysis system that consists of micro channels and polyethersulfone (PES) membranes. However, when blood was used in dialysis experiments, platelets adhered to the surface of membrane and performance of the membrane degraded. Therefore, we modify the surface of PES membranes by coating fluorinated diamond-like carbon (F-DLC). We examined antithrombogencity of the F...
