Hydrolysis of the lignocellulosic biomass results in release high-value chemicals that during industrial processing can be recovered with membrane technologies. To maintain an effective performance membranes used technological biomass, their regular cleaning is essential. Although several guidelines may found for cases organic fouling, data fouled by hydrolyzed limited. Current research aimed t...
Membrane separation is known as an efficient technique for the oily wastewater treatment. Therefore, in the present study, sulfonated poly (ether ether ketone) (SPEEK) was introduced into the polysulfone (PSF) solution in order to enhance the hydrophilicity and the membrane structure for the oil–water separation. The hollow fiber membranes were fabricated via a phase-inversion process. The memb...
The polysulfone-based membrane has been used in hemodialysis (HD) and it is continuously developed to maintain its sustainability on the subject of biocompatibility. During the polysulfone-based membrane development, several parameters should be considered to improve the membrane performances, such as excellent biocompatibility, appropriate ultrafiltration rate, and effective clearance of the t...
L-Phenylalanine (L-Phe) and D-Phenylalanine (D-Phe) imprinted poly [(acrylonitrile)-co-(acrylic acid)] membranes were prepared by wet phase inversion method for chiral separation. The chiral separation ability of molecularly imprinted copolymer membranes towards the underivatized D,L-Phe aqueous mixture was evaluated by ultrafiltration experiment. The novel membranes show continuous permselecti...
