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) ...
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] ...
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 ...
Mechanism of adsorption of Cu2+ and Zn2+ on the corn silk (Zea mays L.)
(Elsevier, Amsterdam, 2017)
In this study the novel biosorbent - raw corn silk (CS) was investigated for Cu2+ and Zn2+ removal from aqueous solutions. The physical and chemical properties of CS were determined by SEM - EDX and ATR - FTIR techniques. ...
Efficient multistep arsenate removal onto magnetite modified fly ash
(Academic Press Ltd- Elsevier Science Ltd, London, 2018)
The modification of the fly ash (FA) by magnetite (M) was performed to obtain FAM adsorbent with improved adsorption efficiency for arsenate removal from water. The novel low cost adsorbents are characterized by liquid ...
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 ...
Further insight into the mechanism of heavy metals partitioning in stormwater runoff
(Academic Press Ltd- Elsevier Science Ltd, London, 2016)
Various particles and materials, including pollutants, deposited on urban surfaces are washed off by stormwater runoff during rain events. The interactions between the solid and dissolved compounds in stormwater runoff are ...
Amides as a model system of low molar mass algal organic matter. Influence on the adsorption of p-nitrophenol on activated carbon
(Elsevier, Amsterdam, 2020)
In this study, the adsorption equilibrium and diffusivity parameters of p-nitrophenol were estimated for water containing different concentrations of secondary amides. Commercial powdered activated carbon was used as an ...
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 ...
