The Factors on Removal of Zinc Cation from Aqueous Solution by Bentonite
Bentonite Zn2+ Adsorption
2013/3/8
The removing zinc cation from aqueous solution by Ca-bentonite and Na-exchanged bentonite was studied. The factors such as the initial concentration of Zn2+, the liquid-to-solid ratio, pH, adsorption ...
Isolation and Characterization of a Smectite as a Micro-Mesoporous Material from a Bentonite
Bentonite mineralogy porosity purification smectite suspension
2010/4/21
A procedure was assessed for obtaining an optimum amount of a micro-mesoporous material known as smectite from Reşadiye (Tokat/Turkey) bentonite. The procedure, which will permit a better economi...
Investigation of the Surface Acidity of a Bentonite Modified by Acid Activation and Thermal Treatment
Acid activation bentonite n-butylamine pore volume surface acidity surface area thermal treatment
2010/4/21
The adsorption of n-butylamine from its solution in cyclohexane on acid-activated and thermally treated Kütahya/Turkey bentonite (KB) samples was followed using a UV-VIS spectrophotometric method. The...
The Effect of Acid Activation on Some Physicochemical Properties of a Bentonite
Acid Activation Bentonite Cation Exchange Capacity Pore Volume Surface Area
2010/4/22
A white calcium bentonite (CaB) from the K\"{u}tahya region/Turkey was activated by heating it for 6 hours at 97°C in H2SO4 solution. The mass percentage of H2SO4 in the bentonite-acid mixture was var...
Thermogravimetric Investigation of the Dehydration Kinetics of KSF, K10 and Turkish Bentonite
Dehydration kinetics Bentonite KSF K10 Ozawa method Coats-Redfern method
2010/4/23
The kinetic parameters for the dehydration of bentonite from Turkey, KSF and K10 were determined by using dynamic TG techniques. The Ozawa method is better for the dehydration of the clay samples than...
Investigation of the Microporous and Mesoporous Structures of the Reşadiye (Tokat/Turkey) Bentonite and its Fractions
Adsorption Bentonite Montmorillonite Porosity, Surface Area
2010/6/27
It was determined by X-ray diffraction that, besides containing clay minerals such as montmorillonite and illite, the original bentonite contained also clinoptilolite, opal-C, quartz, calcite and dol...
Adsorption of Some Textile Dyes by Hexadecyltrimethylammonium Bentonite
Organoclay Textile dyes Adsorption isotherms Langmuir equation Dubinin-Rasdushkevich (D-R) equation
2010/6/27
In this study, hexadecyltrimethylammonium (HDTMA) bentonite was synthesized by placing alkylammonium cation onto bentonite. Adsorption of some textile dyes such as Everdirect Supra Yellow PG, Everdire...
The characterization of Na2 CO3 Activated Kütahya Bentonite
Bentonite montmorillonite surface properties CEC drilling muds
2010/6/30
A calcium bentonite from Kütahya region (Turkey) was activated with Na2CO3 at various ratios (1, 2, 2.5, 5, 10, 15g / 100 g bentonite). Due to ion exchange, the original Ca-bentonite was converted to ...
Nonyl-and Dodecylamines Intercalated Bentonite and Illite From Turkey
Nonyl-and Dodecylamines Intercalated Bentonite Illite From Turkey
2010/6/29
Bentonite and illite were interacted with nonyl- and dodecylammonium salt solutions to see how the alkylammonium ions became attached and oriented within the interlamellar space of the clays. X-ray di...
