METHOD OF PREPARING CARBON SORPTION NANOMATERIAL FROM BIOCHAR BY ELECTROMAGNETIC METHOD Russian patent published in 2023 - IPC C01B32/366 B01J20/20 B01J20/34 C02F1/28 

FIELD: sorption chemistry.

SUBSTANCE: following has been proposed: a method of preparation of carbon sorption nanomaterial from biochar in an electromagnetic way, including obtaining the original biochar from rice husk by carbonization of the original rice husk in a muffle furnace at a temperature of 600°C for 30 minutes with pre-washing, processing of the resulting initial biochar from rice husk in a process activation apparatus for processing materials, according to which a sample of the resulting initial biochar from rice husk was mixed in distilled water and exposed to a rotating electromagnetic field with ferromagnetic particles m=200 g for 30 seconds in a process activation apparatus for processing materials, after which it was dried in an oven for 4 hours at t=105°C.

EFFECT: obtaining an effective sorbent using the method preparation of carbon sorption nanomaterial from biochar by the electromagnetic method with its subsequent use for the purification of natural and wastewater at municipal and industrial facilities.
