FIELD: process engineering.
SUBSTANCE: invention relates to production of antibacterial filtration materials and can be sued in complex water treatment etc. Filtration material comprises polymer material, a base, produced by aerodynamic dispersion of polymer melt from the group made up of polypropylene, polycarbonate or PTF with fiber diametre of 0.1-60 mcm whereon silver particles are secured to cover 5-15% of aforesaid base. Proposed method comprises treatment of the base by water solution of silver salt, reduction of silver ions to produce silver nanoparticles on the base surface by photo activation and microwave-radiation treatment, and rinsing by demineralised water, and drying.
EFFECT: low hydraulic drag and high adsorption properties, reduced water consumption on material production.
