Equilibrium and kinetics study on hexavalent chromium adsorption onto diethylene triamine grafted glycidyl methacrylate based copolymers
(Elsevier Science Bv, Amsterdam, 2012)
Two porous and one non-porous crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) [abbreviated PGME] were prepared by suspension copolymerization and functionalized with diethylene triamine [abbreviated ...
Viscoelastic properties and antimicrobial activity of cellulose fiber sheets impregnated with Ag nanoparticles
(Elsevier Sci Ltd, Oxford, 2012)
A silver nanoparticle colloid was prepared by a modified Tollens method using D-glucose as the reduction agent. The obtained nanoparticles were used for the modification of pine, linter and recycled cellulose fibers. ...
Novel kinetic model of the removal of divalent heavy metal ions from aqueous solutions by natural clinoptilolite
(Elsevier, Amsterdam, 2012)
Removal of heavy metal ions from aqueous solutions using zeolites is widely described by pseudo-second order kinetics although this model may not be valid under all conditions. In this work, we have extended approaches ...
Decolorization of textile dye CI Basic Yellow 28 with electrochemically generated active chlorine
(Elsevier Science Sa, Lausanne, 2012)
Reaction of the indirect electrochemical decolorization of cationic textile dye CI Basic Yellow 28 with electrochemically generated "active chlorine" has been studied, using UV-Vis spectrophotometry, ion chromatography, ...
Mechanism and dynamics of shrinking island grains in mazed bicrystal thin films of Au
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
This work investigates the mechanism and dynamics of grain boundary migration driven by capillary forces via in situ electron microscopy, complemented by molecular-dynamics simulations. Using thin films of Au with the mazed ...
Microstructure evolution of a modified AA5083 aluminum alloy during a multistage homogenization treatment
(Elsevier Science Inc, New York, 2012)
The microstructure evolution of the industrially cast AA5083 modified aluminum alloy during the multistage homogenization treatment was investigated by means of optical, SEM and TEM imaging and microanalysis techniques. ...
Aspects of energy reduction by autogenous copper production in the copper smelting plant Bor
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
This work presents a comparative analysis of the energy consumption during copper production by the "standard" procedure (roasting in a fluo-solid reactor and smelting in a reverberatory furnace) in the Smelting Plant in ...
Amine activators influence on grafting reaction between methacrylic acid and starch
(Elsevier Sci Ltd, Oxford, 2012)
The aim of this work was synthesis of grafted copolymers of poly(methacrylic acid) and starch (PMAA-graft-starch) with high percentage of grafting, G (%). The effect of temperature (55-75 degrees C), concentration of ...
Application of carbonized hemp fibers as a new solid-phase extraction sorbent for analysis of pesticides in water samples
(Elsevier Science Sa, Lausanne, 2012)
There is a growing interest in utilization of abundantly available materials, bio-mass or industrial byproducts, as precursors for the preparation of carbon materials. Short hemp fibers, acquired as waste from textile ...
Effect of different fermentation parameters on L-lactic acid production from liquid distillery stillage
(Elsevier Sci Ltd, Oxford, 2012)
Expansion of lactic acid applications, predominantly for the preparation of biodegradable polymers increased the research interest for new, economically favourable production processes. Liquid stillage from bioethanol ...
