The Mechanism of Acid Activation of Montmorillonite
(TÜBİTAK Yayınları, 1991-01)
β-Carotene adsorption on acid-activated montmorillonite
The adsorption of β-carotene from solution in benzene on acid-activated Canakkale montmorillonite of Turkey has been investigated. The adsorption isotherm had two steps. The first step was of the Langmuir type, and the ...
Thermal investigation of acid-activated clay minerals
Samples of the clay mineral from the Çanakkale reserve in Turkey were activated with sulphuric acid under three different sets of conditions. DTA and TG curves of both natural and activated samples were then obtained and ...
The mechanism of β- Carotene adsorption on activated montmorillonite
The variations in the structure of mineral during adsorption have been examined comparing the results of X-ray diffraction (XRD), differential thermal analysis (DTA), thermogravimetry (TG) and infrared (IR) spectroscopy ...
Kinetics of the thermal dehydration of acid-activated montmorillonite by the rising temperature technique
The activation energies of dehydration and combustion of organic materials in a clay sample, and of dehydration of natural and acid-activated montmorillonite have been determined using a rising temperature programme ...
