Characterization of natural- and organo-bentonite by XRD, SEM, FT-IR and thermal analysis techniques and its adsorption behaviour in aqueous solutions
(Mineralogical Soc, 2012)
In this study, natural bentonite was modified with hexadecyltrimethylammonium (HDTMA) bromide to obtain organobentonite (HDTMA-bentonite). Bentonite and HDTMA-bentonite were then characterized using XRD, XRF, SEM, FT-IR, ...
Adsorption of Acid Blue 193 from aqueous solutions onto Na-bentonite and DTMA-bentonite
(Academic Press Inc Elsevier Science, 2004)
Dodecyltrimethylammonium bromide-modified bentonite (DTMA-bentonite) was prepared and tested as an adsorbent for an acid dye (Acid Blue 193, AB 193) removal from aqueous solution in comparison with Na-bentonite. The effect ...
Adsorption of Acid Blue 193 from aqueous solutions onto BTMA-bentonite
(Elsevier Science BV, 2005)
The adsorption of Acid Blue 193 (AB193) onto benzyltrimethylammonium (BTMA)-bentonite was investigated in aqueous solution in a batch system with respect to contact time, pH and temperature. The surface modification of ...
Modification of bentonite with a cationic surfactant: An adsorption study of textile dye Reactive Blue 19
(Elsevier Science BV, 2007)
The utilization of modified bentonite with a cationic surfactant (dodecyltrimethylammonium (DTMA) bromide) as an adsorbent was successfully carried out to remove a synthetic textile dye (Reactive Blue 19 (RB 19)) by ...
Adsorption kinetics and isotherm parameters of naphthalene onto natural- and chemically modified bentonite from aqueous solutions
(Springer, 2013)
Polycyclic aromatic hydrocarbons (PAHs) have widely been studied and a special concern because of their mutagenic and carcinogenic activities. In this study, natural- and chemically modified-bentonite were characterized ...
Thermal behavior and immersion heats of selected clays from Turkey
(Springer, 2009)
Four clays (two bentonites and two kaolinites) from Turkey were investigated by X-ray diffraction (XRD), thermal analysis (DTA/TG-DSC) and surface area measurement techniques. Mineralogically bentonite samples were ...
Evaluation on dye removal capability of didodecyldimethylammonium-bentonite from aqueous solutions
(Taylor & Francis Inc, 2017)
The removal efficiency of Reactive Blue 19 (RB19) by using surfactant-modified bentonite (MB) from aqueous solutions, and also textile wastewater samples was examined. Natural bentonite (NB) was firstly modified with ...
Immobilization of 2,2 '-dipyridyl onto bentonite and its adsorption behavior of copper(II) ions
(Elsevier Science BV, 2009)
In this study, the immobilization of 2,2'-dipyridyl onto bentonite was firstly carried out and it was then used for the adsorption of copper(II) ions from aqueous solutions. The variation of the parameters of pH, contact ...
Adsorption of lead(II) ions onto 8-hydroxy quinoline-immobilized bentonite
(Elsevier Science BV, 2009)
In this Study, the immobilization of 8-hydroxy quinoline onto bentonite was carried out and it was then used to investigate the adsorption behavior of lead(II) ions from a(aqueous solutions. The changes of the parameters ...
Fourier Transform Infrared, Solid-State Nuclear Magnetic Resonance, and X-Ray Diffraction Studies of Natural and Acid-Treated Bentonites from Turkey
(Taylor & Francis Inc, 2013)
The Fourier transform infrared (FT-IR) technique is widely used to distinguish structural properties and to derive information about structural changes following the chemical modification of clays in different conditions. ...
