In oredr to reduce costs and save time for the membrane manufacturing process, it is necessary to improve the quality of membranes by modeling usage. In this study, Flory Huggins model was used to predict quaternary-system containing polyether sulfone, N-Methyl-2-pyrrolidone, water and used alkanes as an additive. Due to the solubility parameters and molar alkane volumes, the interaction parame...

This report describes a versatile and robust microreactor for bioactive proteins physically immobilized on a polyether sulfone filter. The potential of the reactor is illustrated with glucose oxidase immobilized on a filter with a cut-off value of 30 kDa. A flow-injection system was used to deliver the reactants and the device was linked on-line to an electrochemical detector. The microreactor ...

The modifications of properties sub...

BACKGROUND Bisphenol A (BPA) is an applied chemical that is used in many industrial fields and is a potential endocrine disruption chemical (EDC) that is found in the environment. Bisphenol S (BPS) and polyethersulfone (PES) have been suggested as putative BPA alternatives. In this study, the estrogenic potency induced by the binding of 17-beta-estradiol (E2), BPA, BPS, PES and their metabolite...

Endowing anti-fouling capabilities to water treatment membranes is a key feature for their long lifetime, but it continues be challenging task. Herein, strategy preparing composite reported comprising halloysite nanotubes (HNTs) as scaffolds support ruthenium substituted polyoxometalate (Ru4POM), with the goal of using evolved O2, resulting from Ru4POM-catalyzed H2O2 dismutation, agent. Two dif...

New isoporous nanofiltration composite membranes were fabricated by photo-polymerization of thin films the hexagonal columnar mesophase supramolecular complex 43TB. This was followed deposition on a polyether sulfone macro-porous support and removal template molecule. The had an average permeability 2.3 L m-2 h-1·bar-1 sharp molecular weight cut-off around 5000 g mol-1 based PEG filtration. ful...
