A Novel ceramic tubular membrane coated with a continuous graphene-TiO2 nanocomposite thin-film for CECs mitigation
(Chemical Engineering Journal, 2022)
This work presents a ceramic tubular membrane coated with a continuous graphene-TiO2 nanocomposite thin-film for contaminants of emerging concern (CECs) removal from synthetic and real matrices in single-pass flow-through ...
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 ...
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 ...
Dependence of slip velocity on operating parameters of air-lift bioreactors
(Elsevier Science Sa, Lausanne, 2007)
In this study we analyzed the quality of local mixing in external loop air-lift bioreactors for two hydrodynamic regimes in terms of slip velocity. In particular. the effects of design and operating parameters (e.g., reactor ...
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) ...
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 ...
Electrochemical oxidation of iodide in aqueous solution
(Elsevier Science Sa, Lausanne, 2006)
Electrochemical oxidation of iodide on DSA (Ti/RuO2) anode was investigated in laboratory cell and semi-industrial electrochemical reactor. Anodic polarization curves in the laboratory cell were obtained in solutions ...
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 ...
Arsenate adsorption on waste eggshell modified by goethite, alpha-MnO2 and goethite/alpha-MnO2
(Elsevier Science Sa, Lausanne, 2014)
An efficient adsorbents for arsenate removal was developed by modification of calcined eggshell with goethite (calcined eggshell/goethite; sorbent 1), alpha-MnO2 (calcined eggshell/alpha-MnO2; sorbent 2) and hybride system ...
