Comparative study of cu(2+) adsorption on a zeolite, a clay and a diatomite from Serbia
(Applied Clay Science, 2009)
The adsorption of a zeolite, clay and diatomite from Serbia toward aqueous Cu2+ ions was studied, at different pH. The adsorbents were characterized with respect to phase composition, specific surface area and point of ...
Surface characterization of macroporous glycidyl methacrylate based copolymers by inverse gas chromatography
(European Polymer Journal, 2005)
Two samples of macroporous crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate), PGME, with different porosity parameters were synthesized by suspension copolymerization and modified by ring-opening ...
Simultaneous removal of Pb2+, Cu2+, Zn2+ and Cd2+ from highly acidic solutions using mechanochemically synthesized montmorillonite-kaolinite/TiO2 composite
(Applied Clay Science, 2015)
The aim of the present study was to synthesize a composite of raw interstratified montmorillonite-kaolinite clay (Mt-K) with TiO2 as an additive by mechanochemical activation and investigate its usability as low-cost ...
Surfactant modification and adsorption properties of clinoptilolite for the removal of pertechnetate from aqueous solutions
(Journal of Radioanalytical and Nuclear Chemistry, 2016)
Natural clinoptilolite modified with a cationic surfactant stearyldimethylbenzylammonium chloride (SDBAC) was used as an adsorbent for the removal of pertechnetate from aqueous solutions. Adsorption studies were performed ...
Removal of pertechnetate from aqueous solution using activated pyrolytic rubber char
(Journal of Radioanalytical and Nuclear Chemistry, 2017)
Low-cost adsorbents, synthesized by pyrolysis of waste rubber (CR) and activated with KOH (CRA), have shown the high removal ability of from aqueous solutions in wide range of pHs (2-10) with fast adsorption rate. The ...
Adsorption of nicotine from aqueous solution onto hydrophobic zeolite type USY
(Applied Surface Science, 2011)
The isothermal adsorption of nicotine from an aqueous solution onto zeolite type USY was investigated. The adsorption isotherms of nicotine onto the zeolite at different temperatures ranging from 298 to 322K were determined. ...
Preparation and characterization of zinc-exchanged montmorillonite and its effectiveness as aflatoxin B-1 adsorbent
(Materials Chemistry and Physics, 2012)
A zinc-exchanged montmorillonite (Zn-MONT) was prepared from a natural montmorillonite (MONT) and the adsorption of aflatoxin B-1 (AFB(1)) was investigated at pH 3 and 7. Characterization of Zn-MONT was done by determination ...
Adsorption of phenol and 2,4-dinitrophenol on activated carbon cloth: The influence of sorbent surface acidity and pH
(Separation Science and Technology, 2006)
In this work the effect of the activated carbon cloth surface acidity and pH of the solution on phenols adsorption has been studied. Two phenols, widely different in the terms of their pKa values (phenol and 2,4-dinitrophenol), ...
Mechanism of sorption of pertechnetate onto ordered mesoporous carbon
(Journal of Radioanalytical and Nuclear Chemistry, 2014)
Ordered mesoporous carbon (OMC) was used as an adsorbent for the removal of pertechnetate (TcO4 (-)) anion. The maximum uptake (93 %) of TcO4 (-) was obtained after 60 min of contact. The adsorption of TcO4 (-) is almost ...
Photocatalytic Degradation of Dye CI Direct Blue 78 Using TiO2 Nanoparticles Immobilized on Recycled Wool-Based Nonwoven Material
(CLEAN - Soil Air Water, 2013)
This paper discusses the possibility of immobilization of TiO2 nanoparticles onto recycled wool-based nonwoven material, which can be utilized for removal of dyes from wastewater. The photocatalytic activity of TiO2 ...
