PHYSICO-CHEMICAL STUDIES OF NATURAL ZEOLITE OF NAKHCHIVAN

Abstract

The studeid of physico-chemical properties of natural zeolite of Nakhchivan. On the basis of the data IR-spectroscopic, X-ray diffraction, elemental and derivatographic methods analysis it was found which group of zeolites include natural sample, its composition, the thermal stability, impact ion exchange on the thermal stability, the region of dehydration. The structure of zeolites defines an interior volume, that becomes available after dehydration. The dehydrated zeolite is a crystalline body, riddled with micropores. In the dehydrated state zeolites exhibit its maximum adsorption, molecular sieve and catalytic properties. The ion exchange capacity of zeolites - one of the main parameters that characterize their sorption and technological properties. Ion exchange on zeolites is possible to isolate ions, removing another method which is often of great complexity
