On March 10, 2016 at 12:00, presentation ‘Development of scientific bases for obtaining nano-zeolite sorbents’ took place at Petre Melikishvili Institute of Physical and Organic Chemistry, Iv.Javakhishvili Tbilisi State University. Number of scientists and researchers in a field of Chemistry and Nanochemistry attended the meeting.  The presentation was followed by discussion (Questions and Answers), where future prospects were determined.

Nanuli Dolaberidze, Doctor of Chemical Sciences, Chief Research Worker at Petre Melikishvili Institute of Physical and Organic Chemistry, Iv.Javakhishvili Tbilisi State University gave general overview of the project.

The project was about creation of theoretical and experimental base for obtaining fine-dispersion samples of natural zeolites through alternate method, in particular by chemical treatment. The main direction of the research was the development of scientific grounds for making zeolite nano-materials, which includes determination of some regularity of gel-formation, hydrothermal crystallization and chemical modification processes going on in aluminum silicate systems, which will provide creation of highly efficient, pure zeolite nano-materials, which are highly demanded. The following cheap and easily obtainable natural zeolites from Georgian mines used in the research: clinoptilolite from Rkoni, phillipsite from Shukhuti, analcime from Gelati.

Research objectives pursued were – study of technology of making gels obtained by recrystallization of natural zeolites of Georgia and creation of hydrothermal crystallization model, determination of optimal terms for basic, thermal and ion-exchange treatment.

Based on the collected information, clear, highly dispersed faujasite and mordenite-like zeolite as well as prolonged reaction silver, gold, copper and zinc sorbents, having antibacterial and antivirus features, obtained by justified economic methods. Specialists can use those materials in different fields of medicine, including surgery and dentistry.
