METHOD FOR PRODUCTION OF SORBENT BASED ON COMMON REED Russian patent published in 2020 - IPC B01J20/30 B01J20/20 B01J20/24 

FIELD: water and air purification technology.

SUBSTANCE: invention relates to a method for producing a sorbent based on cane, which can be used for cleaning aqueous media, emergency oil and petroleum product spills in water bodies, as well as for collection of oil products from soil and other surfaces near petrol stations. Method includes mowing of reed vegetative mass during period of physiological rest of cane at stable negative ambient temperatures, mowing of chamfered mass to particle size of 5–10 mm, pyrolysis of ground mass in muffle furnace at temperature 500 °C for 1 hour, hydrolysis with 1 M citric acid solution, neutralization of 5 wt % sodium bicarbonate solution, washing with distilled water and drying to constant weight.

EFFECT: invention enables to obtain a sorbent characterized by high sorption capacity and enables to increase the degree of purification of water from oil products.
