Structural and surface modification of highly ordered alumina for enhanced removal of Pb2+, Cd2+ and Ni2+ from aqueous solution
(Desalination Publ, Hopkinton, 2020)
The adsorption performance of three-dimensionally ordered macroporous (3DOM) alumina doped with iron oxide, and subsequently modified with (3-aminopropyl)triethoxysilane (APTES), FeAl2O3 and FeAl(2)O(3)APTES, was used for ...
Removal of organic and inorganic pollutants from aqueous solutions using starch-diatomaceous earth adsorbent
(Belgrade : The Academy of Applied Technical Studies "Belgrade", 2023)
Organic and inorganic pollutants, accumulated in the environment, could pose a potential danger to living organisms. Some of these pollutants negatively affect the physiological activities of living organisms, and in certain ...
Advanced thermodynamic approach to adsorption of charged adsorbates from aqueous electrolyte solutions
(Elsevier B.V., 2024)
This study present estimation of the thermodynamic parameters and the influence of ionic activity coefficient on the thermodynamic equilibrium constant of adsorption of phosphates on fly ash. The adsorption was conducted ...
Adsorption of arsenate on iron(III) oxide coated ethylenediamine functionalized multiwall carbon nanotubes
(Elsevier Science Sa, Lausanne, 2012)
New criteria in assessing the quality of drinking water reduced the maximum permissible concentration of arsenic from 50 mu g L-1 to 10 mu g L-1 and set a requirement for the development of new technologies for arsenic ...
Production of activated carbon derived from waste hemp (Cannabis sativa) fibers and its performance in pesticide adsorption
(Elsevier, Amsterdam, 2015)
The main objective of this work was to find optimal production parameters for the preparation of activated hemp fibers (ACh) with good adsorption properties toward pesticides. In order to examine the role of manufacturing ...
Surface characterization of mesoporous carbon cryogel and its application in arsenic (III) adsorption from aqueous solutions
(Elsevier, 2015)
Resorcinol-formaldehyde (RF) cryogels were synthesized by sol-gel polycondensation of resorcinol with formaldehyde and freeze-drying was carried out with t-butanol. Carbon cryogel (CC) was obtained by pyrolyzing RF cryogels ...
Removal of Estrone, 17 beta-Estradiol, and 17 alpha-Ethinylestradiol from Water by Adsorption onto Chemically Modified Activated Carbon Cloths
(Korean Fiber Soc, Seoul, 2020)
This paper explores the applicability of unmodified and chemically modified activated carbon cloths (ACCs) for the removal of estrone, 17 beta-estradiol, and 17 alpha-ethinylestradiol from water. In order to examine the ...
Preparation and Characterisation of Novel Biodegradable Material Based on Chitosan and Poly(Itaconic Acid) as Adsorbent for Removal of Reactive Orange 16 Dye from Wastewater
(Springer Int Publishing Ag, Cham, 2015)
Environmental protection has been a topic of great interest in recent years. Discharging azo dyes in aquatic systems contaminates water and causes serious ecological problems. Azo dyes are bio-accumulative, and, due to ...
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 ...
