Preparation and Characterization of an Antifouling Polyethersulfone Nanofiltration Membrane Blended with Graphene Oxide/Ag Nanoparticles

Graphene oxide/Ag nanoparticles (Ag/GO) was prepared and employed to synthesize antifouling polyethersulfone (PES) mixed matrix membranes. The performance of the membranes was evaluated in terms of flux, hydrophilicity and anti-biofouling properties. With increment of the Ag/GO from 0 to 0.1 wt.%, the pure water flux increased from 24.7 up to 54.1 kg/m2 h. The flux recovery ratio (FRR) of the m...

Improved antifouling properties of polyamide nanofiltration membranes by reducing the density of surface carboxyl groups.

Carboxyls are inherent functional groups of thin-film composite polyamide nanofiltration (NF) membranes, which may play a role in membrane performance and fouling. Their surface presence is attributed to incomplete reaction of acyl chloride monomers during the membrane active layer synthesis by interfacial polymerization. In order to unravel the effect of carboxyl group density on organic fouli...

Electrochemical and Antioxidant Properties of Biogenic Silver Nanoparticles

The Present Bio-synthesis is an efficient, fast, cheap, nontoxic, simple and eco-friendly protocol for silver nanoparticles synthesis, which is more beneficial than commonly used physiochemical methods. Here in silver nanoparticles are biosynthesized using Citrus sinensis var. Kozan yerly fruit juice as reducing and stabilizing agent. The X-ray diffraction (XRD) pattern confirms the crystalline...

Antimicrobial properties of a novel silver-silica nanocomposite material.

Nanotechnology enables development and production of novel silver-based composite materials. We used in vitro tests to demonstrate the antimicrobial activity of a silver-silica nanocomposite compared to the activities of conventional materials, such as silver nitrate and silver zeolite. A silver-silica-containing polystyrene material was manufactured and shown to possess strong antimicrobial pr...
