The article presents the results of developing carbon-silicon sorbents that demonstrate high efficiency in capturing various types of dust particles, along with partial antibacterial activity. Dust particles ranging from 0.65 to 150 microns were effectively retained by the sorbent, with organic dust capture efficiency varying between 74% and 98%, making these sorbents suitable for air purification in highly polluted indoor environments. The antibacterial activity was tested on Bacillus paramycoides and Pseudomonas koreensis strains using the diffusion method on a solid nutrient medium. Testing showed that sorbent samples with different concentrations of the active ingredient exhibited varying degrees of bacterial growth suppression, with Sample No. 2 demonstrating the highest activity. Optimizing the sorbent composition and increasing the concentration of active components may enhance its antibacterial properties. These sorbents hold great potential for use in air purification systems with additional protection against bacterial contamination, making them promising for environments with high standards for air hygiene and cleanliness.
