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 ...
Efficient arsenic removal by cross-linked macroporous polymer impregnated with hydrous iron oxide: Material performance
(Elsevier Science Sa, Lausanne, 2015)
Optimization of the synthesis of cross-linked macroporous polymer impregnated with hydrous iron oxide and post-process of obtained material by application of freeze/drying technique, produces high performance adsorbent ...
Optimal conceptual design of processes with heterogeneous catalytic reactors
(Elsevier Science Sa, Lausanne, 2010)
This paper presents an optimisation-based method for the screening and conceptual design of processes with heterogeneous catalytic reactors. The method follows a multi-level approach to process synthesis to establish ...
Aqueous Pb sorption by synthetic and natural apatite: Kinetics, equilibrium and thermodynamic studies
(Elsevier Science Sa, Lausanne, 2010)
Natural apatites represent a cost effective soil amendment, which can be used for in situ reduction of lead bioavailability and mobility. In our previous work, we selected Lisina apatite (LA) as a promising natural mineral ...
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, ...
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. ...
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 ...
Removal of cadmium from aqueous solutions by oxidized and ethylenediamine-functionalized multi-walled carbon nanotubes
(Elsevier Science Sa, Lausanne, 2010)
Surface functionalization of multi-walled carbon nanotubes (MWCNTs) by ethylenediamine, via chemical modification of carboxyl groups, using O-(7-azabenzotriazol-1-yl)-N,N,N',N'-tetramethyluronium hexafluorophosphate, was ...
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 ...
Hydrogel based on chitosan, itaconic acid and methacrylic acid as adsorbent of Cd2+ ions from aqueous solution
(Elsevier Science Sa, Lausanne, 2010)
A hydrogel has been synthesized by ionic crosslinking of chitosan (Ch) with itaconic acid (IA), followed by a free radical polymerization and crosslinking of Ch/IA network by adding methacrylic acid and the crosslinker. ...
