Sažetak
The zeolite clinoptilolite is an alumosilicate material used in many industries and has also medical applications due to its safety in applications in vivo. Due to its crystalline structure with pores and cavities, it is an ion-exchanger that may be useful for certain detoxification purposes in animals and humans. This and other biological effects documented in the scientific literature so far, are most probably related to physio-chemical structure of clinoptilolite materials, especially to the surface properties. We therefore, present herein the surface study of the different clinoptilolite materials by a simple approach of monitoring the surface changes upon interaction of clinoptilolite-materials with sugar solutions. For this purpose, we prepared suspensions of zeolite and added glucose solution in water at concentration of 40g/L. The samples were analysed by use of the Scanning Electron Microscope (SEM) microscope and the results show a dramatic change in the surface area appearance of zeolites in glucose- enriched solutions that may be indicative for formation of novel structures. The Energy Dispersive X-Ray Spectroscopy (EDS) analyses showed that the observed surface structure is mainly composed by oxygen and carbon point to formation of a hydrogel-like sugar structure on the zeolite surface. This behavior will be systematically analyzed in future experiments.
