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...
Alteration of Three Turkish Bentonites by Treatment with Na2CO}3 and H}2SO}4
Bentonite soda activation acid activation
2010/4/22
In this study, fine fractions of bentonites from the Çankırı and Kütahya regions were treated with Na2CO3 and H2SO4. The resulting materials were analysed by X-ray diffraction (XRD), ...
Effect of Acid Treatment on Volumetric Swelling Ratios of Coals
Effect Acid Treatment Volumetric Swelling Ratios of Coals
2010/4/22
To remove Ca2+ ions, six low rank coals and one coking coal were treated with 0.1 and l.0 N HC1 for 24 h. IR spectra and proximate analysis of the lignites indicated that only slight structural change...
Evaluation of sample pre-treatment procedures for the determination of Cr, Ni and V in biological matrices by ETAAS
decomposition electrothermal atomic absorption spectrometry Cr Ni V determination biological materials
2010/4/23
Electrothermal atomic absorption spectrometry (ETAAS) was applied for the determination of chromium, nickel and vanadium in biological materials (earthworms, feather, lucerne). Three different decompo...
Investigations on the Electrochemical Surface Treatment of Carbon Fibers
carbon fiber cyclic voltammetry contact angle
2010/4/23
Desized polyacrylonitrile (PAN) based carbon fibers (CF) were chemically and electrochemically oxidized and reduced. CF surfaces were activated via cyclic voltammetry studies with anodic and cathodic ...
Heat Treatment of Maceral Groups Obtained From Turkish Bituminous Coals
Heat Treatment Maceral Groups Obtained Turkish Bituminous Coals
2010/7/1
The dilatation properties of parent coals and their maceral fractions were examined. In all the coal samples, the main petrographic constituent was the vitrinite maceral. Reflectance of the vitrinite ...
