Sorption of Benzene, Toluene, Ethylbenzene, and Xylene (BTEX) Compounds by Hectorite Clays Exchanged with Aromatic Organic Cations
Adsorptive Organoclays Aromatic Cations BTEX Hectorite Natural Clays Organophilic Organoclays Smectite Sorption Unleaded Gasoline X-Ray
2011/12/7
Abstract: Adsorptive-type organoclays, where hydrocarbons adsorb directly to the siloxane surfaces, were studied to find new organic cations and to determine the parameters that produce effective sorb...
Polymerization of Benzene and Aniline on Cu(II)-Exchanged Hectorite Clay Films: A Scanning Force Microscope Study
Aniline Benzene Hectorite Scanning Force Microscopy
2011/12/27
The technique of scanning force microscopy (SFM) was used to study the nanometer-scale structure of Cu(II)-exchanged hectorite thin films. Supporting data were also obtained from Electron Spin Resonan...
Chemisorption of Benzene on Cu-Montmorillonite as Characterized by FTIR and 13C MAS NMR
Benzene chemisorption 13C MAS NMR Cu-montmorillonite FTIR Poly-p-phenylene
2011/12/1
Abstract: Sorption of benzene onto Cu-montmorillonite was characterized by Fourier transform infrared (FTIR) spectroscopy and 13C magic angle spinning nuclear magnetic resonance (MAS NMR). Under anhyd...
Adsorption of Benzene, Toluene, and Xylene by Two Tetramethylammonium-Smectites Having Different Charge Densities
Adsorption Aromatic hydrocarbons Benzene Charge density Smectite Tetramethylammonium Water
2012/1/4
A high-charge smectite from Arizona [cation-exchange capacity (CEC) = 120 meq/100 g] and a low-charge smectite from Wyoming (CEC = 90 meq/100 g) were used to prepare homoionic tetramethylammonium (TMA...
Reaction of Benzene with Cu(II)- and Fe(III)-Exchanged Hectorites
Adsorption Benzene Copper Electron paramagnetic resonance Free radical Hectorite ?Iron
2012/2/6
The reaction of benzene with exchangeable Cu(II) and Fe(III) in hectorite clay films was studied by electron paramagnetic resonance (EPR). The reaction when carried out in a sealed tube between 60?and...
