Rinsed and thermally treated red mud sorbents for aqueous Ni2+ ions
(Elsevier Science Sa, Lausanne, 2010)
Red mud, an abundant industrial waste from alumina industry, represents a rich source of various metal oxides, mainly of Fe2O3 Al2O3 and SiO2. In this study, the rinsed Bosnian red mud (RBRM) was evaluated as an economical, ...
Synthesis and characterization of poly(2-hydroxyethyl methacrylate/itaconic acid/poly(ethylene glycol) dimethacrylate) hydrogels
(Elsevier Science Sa, Lausanne, 2012)
Hydrogels based on 2-hydroxyethyl methacrylate (HEMA), different poly(ethylene glycol) dimethacrylates (PEGDMA) and itaconic acid (IA) were prepared by free radical crosslinking copolymerization. The influence of different ...
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, ...
SBA-15 templated mesoporous carbons for 2,4-dichlorophenoxyacetic acid removal
(Elsevier Science Sa, Lausanne, 2013)
The ordered mesoporous silica SBA-15 was synthesized and used as a template for obtaining mesoporous carbon replicas. Adsorptive removal of pesticide 2,4-dichlorophenoxyacetic acid (2,4-D) from aqueous solutions onto two ...
The influence of citrate anion on Ni(II) removal by raw red mud from aluminum industry
(Elsevier Science Sa, Lausanne, 2013)
The removal of Ni(II) from aqueous solutions by raw red mud powder was studied in the absence and in the presence of citrate ligand, as a function of process parameters. Using lower initial Ni(II) concentration (10(-3) ...
ZnO/Ag hybrid nanocubes in alginate biopolymer: Synthesis and properties
(Elsevier Science Sa, Lausanne, 2014)
A procedure for the preparation of ZnO nanocubes in an alginate biopolymer was introduced. The obtained nanocubes were used for the preparation of ZnO/Ag heterostructures. High resolution scanning electron microscopy showed ...
Effect of acid treatment on red mud properties with implications on Ni(II) sorption and stability
(Elsevier Science Sa, Lausanne, 2014)
Red mud, a heterogeneous mineral waste from aluminum industry, can be beneficially utilized as a sorbent. High alkalinity and the amount of water soluble ions can limit some of its applications. This study's aim was to ...
Poly(methacrylic acid) based hydrogels as sorbents for removal of cationic dye basic yellow 28: Kinetics, equilibrium study and image analysis
(Elsevier Science Sa, Lausanne, 2013)
Poly(methacrylic acid) based hydrogels with neutralization degree of monomer of 0% (PMAA/0) and 80% (PMAA/80) were synthesized and their sorption potentials toward model cationic dye, basic yellow 28 (BY28), from aqueous ...
Chromium (VI) removal from aqueous solutions using mercaptosilane functionalized sepiolites
(Elsevier Science Sa, Lausanne, 2011)
Natural and acid-activated sepiolite samples were functionalized with (3-Mercaptopropyl)trimethoxysilane. By X-ray powder diffraction, Fourier transform infrared spectroscopy, and differential thermal analysis it was shown ...
Carbon materials from waste short hemp fibers as a sorbent for heavy metal ions - Mathematical modeling of sorbent structure and ions transport
(Elsevier Science Sa, Lausanne, 2014)
Carbonized hemp fibers obtained by carbonization of origin and chemically modified waste hemp fibers was used as a low-cost sorbent for heavy metals removal. The efficiency of carbonized hemp fiber samples as a sorbent was ...
