Hemolitic Activity and Sorption Ability of Beta Zeolite Nanoparticles

The work is devoted to studying the influence of synthesis conditions on the hydrothermal crystallization of zeolite nanoparticles with a Beta structure and studying their properties. The experimentally optimal conditions for the preparation of Beta zeolite nanoparticles of various sizes are determined by varying the temperature and time parameters of the process. The synthesized samples are characterized by X-ray diffraction analysis, scanning electron microscopy, and low-temperature nitrogen adsorption. The sorption ability of zeolite samples of different sizes with respect to inorganic cations (for example, lead ions) and organic molecules (for example, thiamine hydrochloride), as well as their hemolytic activity in relation to human red blood cells, is studied. It is found that the sorption ability of the samples decreases with increasing particle size. For the first time, the results of the dependence of the hemolytic activity of nanoparticles on their size are obtained. Based on the results obtained, conclusions are drawn about the possibility of using nanozeolites in medicine.
