Potential Enrichment of Medicinal Mushrooms with Selenium to Obtain New Dietary Supplements
(Begell House Inc, Danbury, 2013)
The purpose of this study was to resolve the question of whether various selenium concentrations affect the ability of eight species, members of five genera, to produce mycelium biomass and absorb this trace element during ...
Equilibrium, kinetic and thermodynamic studies on removal of Cd(II), Pb(II) and As(V) from wastewater using carp (cyprinus carpio) scales
(Inst Materials Physics, Bucharest, 2013)
Unmodified farming carp (cyprinus carpio) scales were used as a biosorbent for the removal of Cd(II), Pb(II) and As(V) ions from aqueous solutions. The adsorption studies were conducted as a function of pH, contact time ...
Isopiestic determination of the osmotic and activity coefficients of the {yKBr + (1-y)K2HPO4}(aq) system at T=298.15 K
(Academic Press Ltd- Elsevier Science Ltd, London, 2013)
The molality-based osmotic coefficients of aqueous mixtures of KBr and K2HPO4 have been measured at T = (298.15 +/- 0.01) K by the isopiestic method at KBr ionic strength fractions y = (0.18328, 0.38241, 0.58031, 0.79186, ...
Photocatalytic Degradation of Dye CI Direct Blue 78 Using TiO2 Nanoparticles Immobilized on Recycled Wool-Based Nonwoven Material
(Wiley, Hoboken, 2013)
This paper discusses the possibility of immobilization of TiO2 nanoparticles onto recycled wool-based nonwoven material, which can be utilized for removal of dyes from wastewater. The photocatalytic activity of TiO2 ...
VOC emission from oil refinery and petrochemical wastewater treatment plant estimation / Procena emisija lakoisparljivih organskih jedinjenja iz postrojenja za primarni tretman otpadnih voda rafinerijskih i petrohemijskih postrojenja
(Association of Chemical Engineers of Serbia, 2013)
As a consequence of environmental legislation improvement in Serbia for industrial producers, especially future holders of Integrated Pollution Prevention Control (IPPC) license, it is necessary to report annually on ...
Unique effects of microwave heating on polymerization kinetics of poly(methyl methacrylate) composites
(Elsevier Science Sa, Lausanne, 2013)
The effects of heating mode (conventional and microwave) on the kinetics of isothermal polymerization of MMA composite materials were investigated. Isothermal kinetics curves at temperature range from 343 K to 363 K for ...
Bioreactor validation and biocompatibility of Ag/poly(N-vinyl-2-pyrrolidone) hydrogel nanocomposites
(Elsevier Science Bv, Amsterdam, 2013)
Silver/poly(N-vinyl-2-pyrrolidone) (Ag/PVP) nanocomposites containing Ag nanoparticles at different concentrations were synthesized using gamma-irradiation. Cytotoxicity of the obtained nanocomposites was determined by MU ...
Modification of multi-wall carbon nanotubes for the removal of cadmium, lead and arsenic from wastewater
(Inst Materials Physics, Bucharest, 2013)
Multi-wall carbon nanotubes (MWCNTs) was functionalized with 6-arm amino polyethylene glycol (PEG), and synthesized PEG-MWCNTs was used as adsorbent in order to study adsorption characteristics with respect to Cd(II), ...
Impermeable layers in landfill design / Prilog projektovanju vodonepropusnih slojeva deponija
(Association of Chemical Engineers of Serbia, 2013)
Landfills are complex systems that could potentially contaminate the environment. This needs to be prevented by providing impermeability during the landfill design. In this aim, the related regulations should be followed ...
Traffic-related trace element concentrations in PM10 and horse chestnut leaves
(Belgrade : Public Health Institute, 2013)
Urban environment is heavily impacted by airborne particulates originated from fossil fuel
combustion, traffic, industry and other anthropogenic activities. Trace elements, attached to PM10,
can be toxic and may have ...
