abstract

this paper reports on preparation of polyamide membrane with addition of silver nanoparticles (agnps). agnps act as antibacterial agents that are less susceptible to membrane’s biofouling by interfacial polymerization (ip) method. agnps was synthesized via green route which has been reported previously. attenuated total reflectance-fourier transform infrared spectroscopy (atr-ftir), field emission scanning electron microscopy (fesem), contact angle measurement, and energy dispersive x-ray spectrometer (edx) were carried out to characterize the morphology of the prepared membrane samples. inhibition zone of e. coli bacteria was used to study the antibacterial behavior of the membranes. as a result, ftir spectra clearly present the peak of primary amide, secondary amides, carboxyl group and etc. in addition, from the fesem images, it could be seen that relatively regular and spherical shape agnps were formed. contact angle results revealed that the pa membrane is more hydrophilic than that of the pes membrane. edx spectra shows a peak that confirmed the presence of agnps on pa/ag membrane. in antibacterial test, the pa membrane alone could not inhibit the growth of e.coli. membranes with 10 ml and 15 ml loading of agnps added to the m-phenylenediamine (mpd) monomer for the ip process were not enough to kill the e.coli bacteria. the addition of 20ml of agnps to mpd monomer however showed an interesting result as we can clearly observe the inhibition zone in the diameter of 1 mm around the circle of the membrane indicate that all bacteria were totally killed.

Preparation of Novel Thin-Film Composite Nanofiltration Membranes for Separation of Amoxicillin

Several novel composite membranes were prepared to separate and recycle amoxicillin from pharmaceutical wastewater via nanofiltration process. The synthesis of these membranes included three stages: 1- preparation of polysulfone ultrafiltration membranes as a support via phase separation process, 2- modification of its surface by interfacial polymerization as a selective layer (polyamide), and ...

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...

Preparation and Antibacterial Activity of Silver Nanoparticles

Uniform silver nanoparticles have been prepared through the chemical reduction of silver ions by ethanol in presence of sodium linoleate. TEM micrograph shows a uniform distribution of the particles with an average size of 12 nm. Further, the antimicrobial activity of silver nanoparticles shows that these nanoparticles can be used as effective growth inhibitors against Staphylococcus Basillus, ...

Preparation and Characterization of Thin-Film Composite Membrane with Nanowire-Modified Support for Forward Osmosis Process

Internal concentration polarization (ICP) in forward osmosis (FO) process is a characteristic problem for asymmetric thin-film composite (TFC) FO membrane which leads to lower water flux. To mitigate the ICP effect, modification of the substrates' properties has been one of the most effective methods. A new polyethersulfone-based ultrafiltration membrane with increased surface porosity and high...
