Abstract: A preparation method of a high-absorptivity chitosan/bamboo activated carbon composite aerogel include: evenly mixing a chitosan suspension and bamboo activated carbon; dropwise adding glacial acetic acid and stirring to form a solution; dropwise adding a glutaraldehyde solution, and stirring until cross-linking of chitosan is completed; and freezing the obtained liquid in shape, and then performing freeze-drying by means of a vacuum freeze dryer to obtain a chitosan/bamboo activated carbon composite aerogel. The natural, environmentally friendly and degradable chitosan is used as the raw material, bamboo activated carbon is adhered to the chitosan, and the freeze-drying technique is used to prepare the aerogel, so that the bamboo activated carbon is uniformly dispersed and fixed in the three-dimensional space of the aerogel, and the prepared composite aerogel has a high specific surface area and a high porosity, and a high PM2.5 adsorption capacity.
