FIELD: chemistry.
SUBSTANCE: invention relates to methods of producing coated porous particles. Disclosed is a method of producing porous particles, comprising the following steps: (a) providing an aqueous suspension containing a polyamine, a cross-linking agent and a porous organic carrier material in form of particles, at a temperature lower than or equal to 10 °C in a mixer for coating an organic carrier material with a polyamine; (b) cross-linking polyamine and simultaneous removal of water. Also disclosed are porous particles obtained using the disclosed method and embodiments of their use.
EFFECT: obtaining stable and non-combustible absorbent materials for removing heavy metals, acid ions and bacteria.
