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+ ...
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 ...
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 ...
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 ...
Removal of the As(V) and Cr(VI) from the Water Using Magnetite/3D-Printed Wollastonite Hybrid Adsorbent
(International Institute for the Science of Sintering (IISS), 2022)
In this study, the structure, morphology and composition of the synthesized magnetite/3D-printed wollastonite (3D_W/M) composite were characterized, and its adsorption performance with respect to As(V) and Cr(VI) were ...
Spirulina-based carbon bio-sorbent for the efficient removal of metoprolol, diclofenac and other micropollutants from wastewater
(Elsevier, 2022)
This study proposes an efficient activated spirulina-based carbon material (ASBCM800) with an extremely high specific surface area (2211 m2 g−1) to eliminate a wide range of micropollutants (MPs) frequently detected in ...
Arsenic removal by copper-impregnated natural mineral tufa part II: a kinetics and column adsorption study
(Springer Heidelberg, Heidelberg, 2019)
This batch and column kinetics study of arsenic removal utilized copper-impregnated natural mineral tufa (T-Cu(A-C)) under three ranges of particle size. Non-competitive kinetic data fitted by the Weber-Morris model and ...
Effective removal of Reactive Orange 16 dye from aqueous solution by amine-functionalized sepiolites
(Desalination Publ, Hopkinton, 2019)
Natural and acid-activated sepiolites, functionalized by covalent grafting of [ 3-(2-aminoethylamino)propyl]trimethoxy-silane were used as adsorbents for the removal of an anionic Reactive Orange 16 dye from aqueous ...
Kinetics, thermodynamics, and structural investigations on the removal of Pb2+, Cd2+, and Zn2+ from multicomponent solutions onto natural and Fe(III)-modified zeolites
(Springer, New York, 2015)
The adsorption of Pb2+, Cd2+, and Zn2+ from equimolar multicomponent solutions onto natural and Fe(III)-modified zeolites was studied by batch experiments in order to determine the influence of the competitive effect on ...
Characterization of sepiolite by inverse gas chromatography at infinite and finite surface coverage
(Elsevier Science Bv, Amsterdam, 2009)
The adsorption properties of sepiolite from Andrici, Serbia, were studied by inverse gas chromatography at zero and finite surface coverage between 483 and 513 K. The thermodynamic parameters (free energy, enthalpy, entropy) ...
