Adsorption of chromium (VI) from aqueous solutions onto amine-functionalized natural and acid-activated sepiolites
(Elsevier Science Bv, Amsterdam, 2013)
Chromium(VI) adsorption onto amine-functionalized sepiolites from aqueous solution at 298 K was investigated. Natural and add-activated sepiolites were functionalized by covalent grafting [3-(2-aminoethylamino)propyl] ...
Photocatalytic Degradation of Dye CI Direct Blue 78 Using TiO2 Nanoparticles Immobilized on Recycled Wool-Based Nonwoven Material
(Wiley, Hoboken, 2013)
This paper discusses the possibility of immobilization of TiO2 nanoparticles onto recycled wool-based nonwoven material, which can be utilized for removal of dyes from wastewater. The photocatalytic activity of TiO2 ...
Adsorption of lipase from Candida rugosa on multi walled carbon nanotubes
(Elsevier Science Inc, New York, 2013)
In this work lipase from Candida rugosa was adsorbed on unmodified surface of multi walled carbon nanotubes (raw-MWCIsIT). The effects of immobilization time, initial enzyme concentration and buffer ionic strength on enzyme ...
Estimation of competitive adsorption isotherms based on nonlinear frequency response experiments using equimolar mixtures-numerical analysis for racemic mixtures
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
The nonlinear frequency response method for estimation of competitive adsorption isotherms, based on analysis of the response of a chromatographic column to sinusoidal perturbation of the inlet concentration, was modified ...
The adsorption of salicylic acid, acetylsalicylic acid and atenolol from aqueous solutions onto natural zeolites and clays: Clinoptilolite, bentonite and kaolin
(Elsevier, Amsterdam, 2013)
In this study, adsorption of salicylic acid, acetylsalicylic acid and atenolol from aqueous solutions onto clinoptilolite modified with sorbed metallic cations (Cu(II), Zn(II), Ni(II) or Mn(II)) have been probed. Natural ...
Modification of multi-wall carbon nanotubes for the removal of cadmium, lead and arsenic from wastewater
(Inst Materials Physics, Bucharest, 2013)
Multi-wall carbon nanotubes (MWCNTs) was functionalized with 6-arm amino polyethylene glycol (PEG), and synthesized PEG-MWCNTs was used as adsorbent in order to study adsorption characteristics with respect to Cd(II), ...
