BIOCIDE POROUS PARTICLES, ITS PRODUCTION METHOD AND USE Russian patent published in 2022 - IPC A01N33/02 A01N61/00 B01D27/00 B01J20/26 C02F1/28 C02F1/58 

FIELD: microbiology.

SUBSTANCE: invention relates to means of purification from biological contaminations. Biocide porous particles of cross-linked polyamine are obtained, using following stages: (a) provision of an aqueous suspension containing polyamine, cross-linking agent and porous inorganic substrate, which can be solved under aqueous alkaline conditions at pH of more than 10, in the form of particles, at a temperature less than or equal to 10°C in a mixer for the application of polyamine coating to inorganic substrates; (b) cross-linking of organic polymer in pores of inorganic substrate with simultaneous removal of water; (c) dissolution of inorganic substrate to obtain biocide porous particles of cross-linked polyamine. Polyvinyl amine is used as polyamine, and epichlorohydrin is used as a cross-linking agent. Biocide porous particles are used for the purification of water from biological contaminations, such as bacteria, microbes, ferments, fungi, viruses.

EFFECT: proposed biocide porous particles provide high degree of water purification without deterioration of its taste qualities.
