METHOD FOR PRODUCING HERBICIDE STABILISED WITH ACTIVE CARBON Russian patent published in 2021 - IPC B01J20/20 A01N25/08 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of sorbent modification, including impregnation of active carbons (AC), and can be used to suppress weeds in agriculture, gas industry, railway transport, etc. Proposed is a method for producing a herbicide stabilised with active carbon, including preparing an impregnating solution, impregnating active carbon grains thereby, aging and heat treatment. Active carbon with a macropore volume of 0.40 to 0.60 cm³/g and a sorption space volume of 0.30 to 0.35 cm³/g is taken as a basis, impregnation is performed at a ratio of the total pore volume of the active carbon and the impregnating solution of 0.95 to 1.00. Heat treatment is performed at 25 to 50°C during 1 to 2 hours.

EFFECT: invention allows ensuring prolonged action of the herbicide in the soil by reducing stabilisation of the herbicide solution in the porous structure of activated carbon.
