SYNTHESIS AND STUDY OF TEXTURE AND SORPTION CHARACTERISTICS OF MESAPOROUS SILICA GEL MODIFIED BY NANOMAGNETIC MATERIAL Fe3O4

In this paper, we developed a method for synthesizing low-porosity silica gel modified with nanomagnetic material Fe3O4, and studied its textural and sorption characteristics. The resulting material was characterized by low-temperature nitrogen adsorption, X-ray diffraction, and vibration magnetometry. The results showed that the introduction of Fe3O4 nanoparticles improves the adsorption properties of silica gel with respect to organic pollutants and heavy metal ions, while maintaining its textural characteristics.
