Adsorption of NO in clinoptilolite-rich zeolitic mineral by concentration pulse chromatography method
The equilibrium and kinetic parameters for NO adsorption in a clinoptilolite-rich natural zeolitic material from Turkey were determined using the concentration pulse chromatography method. Under the experimental conditions ...
Yapay sindirim sıvısında doğal zeolitlerde meydana gelen morfolojik değişmeler
Doğal zeolitler biyoaktif maddelerdir. Doğal zeolitlerin hayvanlarda biyokütle arttırıcı besi katkı maddesi, insanlarda ülser tedavisinde mide asitliğini tamponlayıcı, asitliği düşürücü ilaç gibi değişik kullanım alanları ...
The effects of natural zeolite and silane coupling agents on melting and crystallization behaviour of polypropylene
The thermal characterization of polypropylene (PP) composites containing untreated and treated zeolite with different silane coupling agents was carried out using thermogravimetric analysis (TG) and differential scanning ...
Natural zeolite polypropylene composite film preparation and characterization
In this research, the preparation and characterization of polypropylene (PP) and natural zeolite composites were studied. Natural zeolite mined in Gördes, Turkey was used as an alternative filler to CaCO3. Films were ...
CO2 and N2 adsorption on the acid (HCl, HNO 3, H2SO4 and H3PO4) treated zeolites
CO2 and N2 adsorption on the acid treated natural and synthetic zeolites at 5◦C and 25◦C was studied. The system heterogeneity was higher for CO2 than N2 adsorption and decreased with acid treatment.
Synergistic effect of metal soaps and natural zeolite on poly(vinyl chloride) thermal stability
(Society of Plastics Engineers, 2005-06)
The synergistic effect of metal soaps (zinc stearate and calcium stearate) and/or natural zeolite (clinoptilolite) on PVC thermal stability was investigated. For this purpose, PVC plastisol was prepared by mixing poly(vinyl ...
Preparation and characterization of antibacterial cobalt-exchanged natural zeolite/poly(vinyl alcohol) hydrogels
In the present study, potential application of the local clinoptilolite-rich natural zeolite in formulation of antibacterial hydrogels was investigated. The zeolite powder exchanged with cobalt(II) ions was used in preparation ...
Aqueous interactions of zeolitic material in acidic and basic solutions
Aqueous interactions of natural zeolitic material in as-received and modified forms were studied. The zeolitic materials was interacted with acidic (hydrochloric acid, lactic acid, acetic acid) and basic (sodium hydroxide) ...
Effect of additives on flexible PVC foam formation
In this study, effects of Ca/Zn stearate and organotin heat stabilizers and zeolite, CaCO3, cellulose and luffa flours fillers, and their concentrations (2.5, 5, 10 and 20% by weight) on production of flexible PVC foams ...
