▎ 摘  要

NOVELTY - Adsorption material has a three-layer structure, which is a biomass graphene layer, a non-woven fabric layer, and a mixed material layer, respectively. USE - Adsorption material used for purifying flue gas from sludge incineration. ADVANTAGE - The adsorption material achieve synergistic treatment, easy to operate, easily available, low cost, simple preparation process, and has degradable adsorption material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing adsorbent material, which involves: (A) dissolving sodium alginate in water to form a solution of sodium alginate; (B) taking chitosan and dissolving in mineral acid solution, after stirring to dissolve completely; (C) adding sodium alginate solution, waste biomass material and calcium-based bentonite, and stir to form a viscous solution; (D) taking biomass graphene and dissolve in dimethylformamide (DMF) solution; and (E) coating the mixed material and the biomass graphene material on both sides of the non-woven fabric respectively, the coating thickness is 0.1-5mm, and the adsorption material is obtained after drying.
