 abstract = {Selenium and copper nanoparticles exhibit superior antioxidant activity,
unique properties, and great potential applications that make them very
attractive for developing new composite materials. In this study,
polyethersulfone (PES) ultrafiltration membrane was modified by
dispersing nano-sized selenium (nSe) and copper (nCu) particles
uniformly in a PES solution (18% polymer weight) and casted by a phase
inversion process. Membranes with four different weight ratios of nSe
and nCu to PES of 0.002, 0.010, 0.030, and 0.050 were tested. Selenium
nanoparticles were prepared by the reduction of aqueous sodium selenite
solution with freshly prepared glucose solution. The method was capable
of producing spherical selenium nanoparticles in a size range of about
150-175 nm, under ambient conditions. The synthesized nanoparticles can
be separated easily from the aqueous solutions by a high-speed
centrifuge and can be re-dispersed in an aqueous medium by an
ultra-sonicator. The effects of temperature, time, and stirring rate on
the size of the selenium nanoparticles were studied. In addition,
nanoscale particles of metallic copper clusters were prepared by
sonochemical reduction of copper(II) hydrazine carboxylate
Cu-(N2H3COO)(2) center dot 2H(2)O complex in an aqueous medium.
Reduction process takes place under an argon atmosphere over a period of
2-3 h and the size of copper nanoparticles was about 90-105 nm. The
synthesized selenium and copper nanoparticles were characterized by
X-ray diffraction (XRD), transmission electron microscopy (TEM), and
particle size distribution techniques. Moreover, Se/PES and Cu/PES blend
membranes were also characterized using contact angle goniometer,
scanning electron microscopy (SEM), and permeation tests. Anti-fouling
performance was examined using activated sludge as a biological
suspension. The protein rejection study was also carried out using the
bovine serum albumin (BSA) solution. The morphology and permeation
properties of the blend membranes were found to be dependent on the
amounts of nanoparticles. Compared to neat PES membrane, the 0.05 Cu/PES
membrane exhibited highest protein rejection ratio (86.3%). However,
the Se/PES membranes showed better antifouling performance (lower flux
decline). The blending membranes with nanoparticles are considered to be
suitable for the prevention of biofouling. (c) 2013 Elsevier B.V. All
