METHOD OF INACTIVATING VIRUSES IN WATER MEDIA Russian patent published in 2014 - IPC C02F1/50 C02F1/28 B01J20/28 C02F103/04 

FIELD: chemistry.

SUBSTANCE: invention can be used for preparation of ultra-pure water, safe for consumption by people, as a result of sorption purification of drinkable water from viruses. Method includes filtration of water through zones with sorption materials, where, at least, one of zones represents porous filtering element based on resins, obtained by condensation of aldehydes with aromatic phenols and amines. Sorption material possesses the following characteristics: ratio of absolute value of zeta potential of porous filtering element to value of effective radius of liquid flow canal constitutes not less than 10⁴ V/m. Porous filtering element, based on resin, obtained by condensation of formaldehyde with resorcin or melamine, is used as such sorption material of, at least, one of zones. Porous filtering element can preferably contain onwashed layer of sorption material, characterised by ratio of absolute value of material zeta potential to value of effective radius of flow canal not less than 10⁵ V/m.

EFFECT: method ensures high degree of neutralisation of viruses.
