Adsorption kinetics, equilibrium, and thermodynamics of Cu2+ on pristine and alkali activated steel slag
(Taylor & Francis Inc, Philadelphia, 2020)
Two adsorbents, pristine electric arc furnace slag (EAFS) and alkali activated slag (AAS) were used for Cu2+ removal from aquatic solutions. Batch adsorption tests were conducted at various temperatures and initial Cu2+ ...
Utilization of agro-industrial waste for removal of copper ions from aqueous solutions and mining-wastewater
(Elsevier Science Inc, New York, 2019)
In this study, unmodified lemon peel, as agro-industrial waste, was used to investigate removal efficiency of copper ions from aqueous solutions and mining wastewater. The effects of solution pH, adsorption time, metal ion ...
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), ...
Enhanced sorption of Cu2+ from sulfate solutions onto modified electric arc furnace slag
(Elsevier Science Bv, Amsterdam, 2019)
Pristine electric arc furnace slag (EAFS) as well as EAFS modified by alkali activation i.e. alkali activated slag (AAS) have found a novel application as adsorbents used in Cu2+ removal from sulfate solutions. The adsorption ...
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 ...
Modeling of disperse dye adsorption on modified polyester fibers
(University of Novi Sad, Faculty of Technology, 2020)
The results of the research on the ability of adsorption of dye on polyester fibers at a temperature of 98 °C are presented in this paper. The fibers were previously modified in aqueous solutions of NaOH, KOH or Al(OH)3. ...
Investigation on the Adsorption of the Carbamate Pesticide Methomyl from Aqueous Solution using Modified Co-Beta Zeolite Particles
(International Institute for the Science of Sintering (IISS), 2023)
Adsorption of carbamate pesticide Methomyl by Co-Beta Zeolite particles prepared by wet ion-exchange method from aqueous solutions was studied. The effect of zeolite and pesticide concentrations, pH value, and sintering ...
Adsorption thermodynamics of organics on nickel- and copper-hexacyanoferrates
(Trans Tech Publications Ltd, Durnten-Zurich, 1998)
Adsorption of various organics on Ni- and Cu-hexacyanoferrates was investigated by gas-solid chromatography (inverse gas chromatography). Adsorption was studied in the temperature region from 80 to 95 degrees C at zero ...
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 ...
