▎ 摘 要
NOVELTY - Manufacturing adsorption material comprises (i) washing sand with water, soaking in hydrochloric acid, performing solid-liquid separation and drying the sand; and (ii) dissolving hexagonal boron nitride/graphene oxide compound in an organic solvent, adding sand, stirring at 100-120 degrees C, spin coating and volatilizing the organic solvent to obtain grey brown adsorption material, where the ratio of sand, hexagonal boron nitride/graphene oxide compound and organic solvent is 5-20 g:0.1-10 g:100-800 ml. USE - The method is useful for manufacturing adsorption material (claimed). ADVANTAGE - The method is simple and economical. The adsorption material has strong adsorption capacity of more than 15 times of its weight. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for adsorption material, comprising sand and hexagonal boron nitride/graphene oxide compound coated on sand surface.
