Applications of non-linear frequency response for investigation of adsorption systems
(Soc Chemists Technologists Madeconia, Skopje, 2009)
Two main directions of application of nonlinear frequency response and the concept of higher order frequency response functions (FRFs) in investigation of adsorption systems are presented, one for development of novel ...
Adsorption of Pb2+, Cd2+ and Sr2+ ions onto natural and acid-activated sepiolites
(Elsevier Science Bv, Amsterdam, 2007)
The adsorption mechanisms of Ph2+, Cd2+ and Sr2+ ions on natural sepiolite and the influence of acid treatment on the adsorption capacity of sepiolite were investigated. The point of zero charge pH(pzc), is 7.4 +/- 0.1 for ...
Adsorption of itaconic acid from aqueous solutions onto alumina / Adsorpcija itakonske kiseline iz vodenih rastvora na aluminijum-oksidu
(Serbian Chemical Society, Belgrade, 2008)
Itaconic acid, IA (C5H6O4), was investigated as a potential flocculant for the aqueous processing of alumina powders. The adsorption of IA, as a function of its concentration and pH value of the solution, onto the alumina ...
Removal of organochlorine pesticides from water using virgin and regenerated granular activated carbon / Uklanjanje pesticida iz vode na granulisanom aktivnom uglju
(Serbian Chemical Society, Belgrade, 2010)
Public water systems use granular activated carbon in order to eliminate pesticides. After saturation, the used activated carbon is regenerated and reused in order to reduce the costs of water production and minimize waste. ...
Adsorptive Removal of Technetium-99 Using Macroporous Poly(GMA-co-EGDMA) Modified with Diethylene Triamine
(Wiley-Blackwell, Malden, 2012)
dThe possibility of sorption of technetium-99 in the form of pertechnetate anion (TcO(4)(-)) and the sorption kinetics for removing TcO(4)(-) from aqueous solution by chelating polymers based on glycidyl methacrylate (GMA) ...
Immobilization of enzymes onto carbon nanotubes / Imobilizacija enzima na ugljenične nanocevi
(Association of Chemical Engineers of Serbia, 2011)
The discovery of carbon nanotubes (CNTs) has opened a new door in nanotechnology. With their high surface area, unique electronic, thermal and mechanical properties, CNTs have been widely used as carriers for protein ...
Arsenic removal from water using low-cost adsorbents - a comparative study / Pregled savremenih metoda za uklanjanje arsena iz vode
(Serbian Chemical Society, Belgrade, 2011)
Inorganic arsenic removal from water using low-cost adsorbents is presented in this paper. Selective removal of As(III) and As(V) from water was performed with natural materials (zeolite, bentonite, sepiolite, pyrolusite ...
The adsorption of imidacloprid onto activated carbon obtained by carbonization of pine cones / Adsorpcija imidakloprida na aktivnom uglju dobijenom karbonizacijom borove šišarke
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2013)
Pine cones of European Black pine are utilized as a precursor for obtaining powdered activated carbon. The concentrated phosphoric acid was used as an activating agent. A detailed study of the imidacloprid adsorption onto ...
Functionalization of thermo-acid activated sepiolite by amine-silane and mercapto-silane for chromium(VI) adsorption from aqueous solutions / Adsorpcija hroma(VI) iz vodenih rastvora na termo-kiselinski aktiviranom sepiolitu funkcionalizovanom amino-silanom i merkapto-silanom
(Association of Chemical Engineers of Serbia, 2013)
Chromium(VI) adsorption from aqueous solutions onto thermo-acid activated sepiolite functionalized with (3-mercaptopropyl)trimethoxy-silane and [3-(2-aminoethylamino)propyl]trimethoxy-silane was investigated. Scanning ...
Separation and determination of dimethylarsenate in natural waters / Razdvajanje i određivanje dimetilarsenata u prirodnim vodama
(Serbian Chemical Society, Belgrade, 2012)
A simple and efficient method for the separation and determination of dimethylarsenate DMAs(V) was developed in this work. Two resins, a strong base anion exchange (SBAE) resin and iron-oxide coated hybrid (HY) resin were ...
