Abstract

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.

β沸石纳米粒子的溶血活性和吸附能力

摘要

这项工作致力于研究合成条件对具有β结构的沸石纳米颗粒水热结晶的影响并研究其性能。通过改变过程的温度和时间参数，可以确定制备各种尺寸的β沸石纳米粒子的实验最佳条件。合成的样品通过X射线衍射分析，扫描电子显微镜和低温氮吸附进行表征。研究了不同大小的沸石样品对无机阳离子（例如，铅离子）和有机分子（例如，硫胺素）的吸附能力，以及相对于人类红细胞的溶血活性。发现样品的吸附能力随着粒度的增加而降低。首次获得纳米颗粒的溶血活性对其大小的依赖性的结果。基于获得的结果，得出关于在医学中使用纳米沸石的可能性的结论。
