Ion Exchange Behavior of Zeolites A and P Synthesized Using Natural Clinoptilolite
The main goal of this study is to investigate the capability of zeolites A and P synthesized from Iranian natural clinoptilolite for uranium uptak. The removal of uranium(VI) from aqueous solution via ion exchange by zeolites in a single component system with various contact times, temperatures and initial concentrations of uranium(VI) was investigated. The experimental results we...
متن کاملThermal Behavior of a Natural Sepiolite from Northeastern Iran
Sepiolite deposits have been recently discovered in northeastern Iran. However, there is still little information about its physicochemical and mineralogical characteristics. Therefore, the collapse of the sepiolite (with sizes of < 63 μm) structure induced by temperature elevation in an electric furnace at 350, 550, and 850 °C for 4 hours was studied using X-ray diffraction (XRD) in combinatio...

متن کاملSynthesis of Zeolites, Merlinoite Minerals of Damavand’s Natural Clinoptiloite Zeolites Mineral in Hydrothermal Conditions, under the Influence of Alkaline
In the present research synthesis of zeolites, merlinoite minerals of natural clinoptiloite mineral in the presence of alkaline mediums, was investigated. The analyzed variants are a result of a concentration of Na+ and K+ ions, temperature and time. Phase transition of clinoptiloite was conducted in the presence of an 8 molar potash solution (KOH) and a 4 molar soda solution (NaOH). Results in...
