Hydrodynamics of shallow fluidized bed of coarse particles
(Elsevier Science Sa, Lausanne, 2005)
The aim of the present study is experimental investigation of hydrodynamics of shallow fluidized bed of coarse particles. Air was fluidizing fluid. gamma-Al2O3 particles of 1 mm and 1.8 mm in diameter and density of 1080 ...
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, ...
Photodegradation of an azo pyridone dye using TiO2 films prepared by the spray pyrolysis method
(Elsevier Science Sa, Lausanne, 2012)
In this study, the feasibility of preparing porous TiO2 films on a stainless steel substrate from a hydrothermally prepared colloidal TiO2 solution by the spray pyrolysis technique is presented. The prepared samples were ...
Removal of lead from water by amino modified multi-walled carbon nanotubes
(Elsevier Science Sa, Lausanne, 2011)
Pristine, oxidized, ethylenediamine, diethylenetriamine and triethylenetetramine modified multi-walled carbon nanotubes (raw-MWCNT, o-MWCNT, e-MWCNT, d-MWCNT and t-MWCNT, respectively) were employed as adsorbents in order ...
Study of factors affecting Ni2+ immobilization efficiency by temperature activated red mud
(Elsevier Science Sa, Lausanne, 2011)
The waste red mud, remaining in remarkable quantities after the digestion of bauxite ores following the Bayer process, contains number of voluble minerals with excellent sorption properties towards aqueous heavy metals. ...
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 ...
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 ...
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, ...
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 ...
Mathematical modeling of heavy metal ions (Cd2+, Zn2+ and Pb2+) biosorption by chemically modified short hemp fibers
(Elsevier Science Sa, Lausanne, 2011)
Biosorption, an innovative and low-cost effective method for removal of heavy metal ions from wastewaters, primarily depends on the diffusion of metal ions through the porous structure of sorbent and the resistance effects ...
