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 ...
Ultrasonic assisted arsenate adsorption on solvothermally synthesized calcite modified by goethite, alpha-MnO2 and goethite/alpha-MnO2
(Elsevier, Amsterdam, 2014)
A highly porous calcium carbonate (calcite; sorbent 1) was used as a support for modification with alpha-FeOOH (calcite/goethite; sorbent 2), alpha-MnO2 (calcite/alpha-MnO2; sorbent 3) and alpha-FeOOH/alpha-MnO2 ...
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), ...
Binary adsorption of nickel and zinc from aqueous solutions onto the Serbian natural clinoptilolite
(Taylor & Francis Inc, Philadelphia, 2016)
Sorption of the Zn2+ and Ni2+ ions by the Na+-enriched natural clinoptilolite (Na-CLI) from aqueous solutions containing both Zn2+ and Ni2+ ions at a range of concentrations has been studied at 298, 308, and 318K. It was ...
Rapid cationic dye adsorption on polyphenol-extracted coffee grounds-A response surface methodology approach
(Elsevier Science Bv, Amsterdam, 2014)
The Box-Behnken design under the response surface methodology (RSM) with five interacting parameters (adsorbent dose, initial dye concentration, time of agitation, initial solution pH and time of the adsorbent microwave ...
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 ...
Efficient As(V) removal by alpha-FeOOH and alpha-FeOOH/alpha-MnO2 embedded PEG-6-arm functionalized multiwall carbon nanotubes
(Inst Chemical Engineers, Rugby, 2017)
A novel adsorbents, 6-arm amino polyethylene glycol functionalized multiwall carbon nanotubes (PEG/MWCNT) loaded with alpha-FeOOH (Fe/PEG/MWCNT), and hybrid alpha-FeOOH/alpha-MnO2 nano-deposit (Fe-Mn/PEG/MWCNT) were used ...
The enhanced removal of cationic dyes in binary system using novel copolymers with two kinds of acidic groups
(Elsevier Science Bv, Amsterdam, 2015)
In this study novel copolymer hydrogels based on methacrylic acid (MAA) and 2-acrylamido-2-methylpropane sulfonic acid (AMPS) were synthesized by free-radical aqueous copolymerization and characterized. Derived P(MAA-co-AMPS) ...
Immobilization of horseradish peroxidase onto kaolin
(Springer, New York, 2016)
Kaolin showed as a very perspective carrier for the enzyme immobilization and it was used for the adsorption of horseradish peroxidase (HRP). The effects of the enzyme concentration and pH on the immobilization efficiency ...
Highly ordered macroporous gamma-alumina prepared by a modified sol-gel method with a PMMA microsphere template for enhanced Pb2+, Ni2+ and Cd2+ removal
(Elsevier Sci Ltd, Oxford, 2017)
The adsorption performance of three-dimensionally ordered macroporous (3DOM) gamma-alumina was investigated for enhanced Pb2+, Ni2+ and Cd2+ removal. The synthesis was based on a modified sol-gel method using a colloidal ...
