Diffusion mechanism of water vapour in a zeolitic tuff rich in clinoptilolite
(Springer, 2008-12)
The adsorption kinetics of H2O in a clinoptilolite rich zeolitic tuff was experimentally investigated at 18°C. In the identification of the diffusion mechanism the isothermal adsorption model equation was used. It was found ...
Kinetics of proton transfer in the zeolitic tuff
(Central European Science Journals, 2009)
The kinetics of a proton transfer into dilute acid solutions containing natural zeolitic tuff was studied by following the pH evolution of the liquid phase. Four different solutions with tuff contents of 9, 3, 1 and 0.5 ...
Cure kinetics of epoxy resin-natural zeolite composites
(Springer, 2008-12)
The cure kinetics of epoxy resin and epoxy resin containing 10 mass% of natural zeolite were investigated using differential scanning calorimetry (DSC). The conformity of the cure kinetic data of epoxy and epoxy-zeolite ...
Clinoptilolite-rich mineral as a novel carrier for the active constituents present in Ginkgo biloba leaf extract
(Elsevier, 2008-06)
The possible use of clinoptilolite-rich mineral as a novel carrier for the active constituents present in Ginkgo biloba leaf extract solutions was investigated. The flavonoid aglycone constituents were found to be selectively ...
Microwave effect on ion-exchange and structure of clinoptilolite
(Springer, 2007-03)
The effect of microwave irradiation on the ion exchange degree and structure of clinoptilolite mineral has been examined in comparison with the conventional heat treatment in waterbath. Clinoptilolite-rich mineral from the ...
The kinetics of citral hydrogenation over Pd supported on clinoptilolite rich natural zeolite
(Elsevier, 2005-06)
The liquid phase hydrogenation of citral has been investigated over Pd (2.42%) supported on clinoptilolite rich natural zeolite catalyst for different reaction conditions. The zeolite support did not affect the active metal ...
The effect of HCl treatment on water vapor adsorption characteristics of clinoptilolite rich natural zeolite
(Elsevier, 2005-01)
In this study, water vapor adsorption properties of the clinoptilolite rich zeolite tuff, from Bigadic (Turkey), and its modified forms were examined. The modified forms were obtained by treating the tuff with HCl solutions ...
A chromatographic study of carbon monoxide adsorption on a clinoptilolite-containing natural zeolitic material
(Taylor & Francis, 2004-11)
In this study, the equilibrium and kinetic parameters for CO adsorption on clinoptilolite-rich natural zeolitic material were determined by the concentration pulse chromatography technique. Experiments were carried out at ...
Silver, zinc, and copper exchange in a Na-clinoptilolite and resulting effect on antibacterial activity
(Elsevier, 2004-10)
Ag+-Na+, Zn2+-Na+, and Cu2+-Na+ equilibria for clinoptilolite-rich mineral from Gördes (Western Anatolia) were investigated at 25 °C and 0.1 N total solution normality. While silver exchange was favorable over the whole ...
Isomerization of α-pinene over calcined natural zeolites
(Elsevier, 2004-06)
In this work, isomerization reaction of α-pinene was studied over several heat-treated natural zeolite catalysts, rich in clinoptilolite, from Balýkesir-Bigadic region in Turkey in a batch slurry reactor under nitrogen ...
