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 ...
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 ...
Clinoptilolite supported rutile TiO2 composites: Synthesis, characterization, and photocatalytic activity on the degradation of terephthalic acid
(Elsevier, 2017-02)
Clinoptilolite supported rutile TiO2 composites were synthesized for the enhancement of its photocatalytic performance in the degradation of the aqueous terephthalic acid solution under UVC illumination by the increase in ...
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 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 ...
