▎ 摘　　要

NOVELTY - Processing agent comprises 50-70 pts. wt. chitosan/doped graphene/cellulose blend aerogel ball, 30-35 pts. wt. porous alumina, 30-35 pts. wt. zeolite and 30-35 pts. wt. activated carbon. USE - The processing agent is useful for removing indoor formaldehyde and indoor volatile organic compound (claimed). ADVANTAGE - The processing agent has good absorption function on toluene, xylene, cyclopentane diene and aldehyde, is economical and highly efficient. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the processing agent, comprising: (i) preparing the modified flake graphene oxide; (ii) doping the graphene with a transition metal; (iii) preparing cellulose solution using reed pulp; (iv) preparing ternary blend aerogel ball; and (v) performing complexing treatment.
