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 ...
Batch and column studies on heavy metal removal using a local zeolitic tuff
(Elsevier, 2010-09)
Ion exchange is considered to be one of the most cost effective methods if low cost ion exchangers such as natural zeolites are used in waste water treatment. In this study, a zeolitic tuff rich in clinoptilolite from ...
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 ...
Characterization and dehydration behavior of a natural, ammonium hydroxide, and thermally treated zeolitic tuff
(Taylor & Francis, 2011-04)
Aqueous NH4OH-treated and subsequently calcined forms of local natural zeolitic tuff were characterized by different techniques including scanning electron microscopy (SEM), X-ray powder diffraction, inductively coupled ...
Investigation of structural properties of clinoptilolite rich zeolites in simulated digestion conditions and their cytotoxicity against Caco-2 cells in vitro
(Springer, 2013-04)
The use of the clinoptilolite rich natural zeolites in biomedical applications such as in anticancer therapy, drug or drug support systems and as nutritive supplement is highly dependent on their behavior in digestive ...
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 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 ...
