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 ...
Fast evaluation of periodic operation of a heterogeneous reactor based on nonlinear frequency response analysis
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
The concept of higher-order frequency response functions (FRFs), which is based on Volterra series representation of nonlineral systems, is used to analyse the time-average performance of a perfectly mixed reactor subject ...
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) ...
Fenitrothion adsorption - desorption on organo - minerals
(Elsevier, Amsterdam, 2011)
The adsorption-desorption of the pesticide fenitrothion on organo-montmorillonite, organo-clinoptilolite and organo-sepiolite was studied at different loadings of stearyl- dimethylbenzylammonium cations (SDBA). The SDBA ...
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 ...
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] ...
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 ...
Regeneration of the ciprofloxacin-loaded clinoptilolite by non-thermal atmospheric plasma
(Elsevier, 2022)
Natural clinoptilolite (CLI) exhibited a high efficacy in ciprofloxacin (CIP) removal from aqueous solution by adsorption. However, the regeneration of the spent adsorbent was a challenge since the adsorption occurred via ...
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 ...
