▎ 摘　　要

NOVELTY - A deodorizing agent comprises 10-15 wt.% chitosan, 5-10 wt.% nano-titanium dioxide, 1-3 wt.% graphene oxide, 0.1-2 wt.% polyvinylpyrrolidone, 1-10 wt.% sodium bicarbonate, 5-15 wt.% polyethylene glycol and balance amount of water. USE - Deodorizing agent for purification of indoor air and removal of formaldehyde from indoor air. ADVANTAGE - The deodorizing agent is nontoxic and safe, effectively removes formaldehyde from indoor plates and other indoor materials, and has long-lasting deodorizing effect, improved formaldehyde-removing effect, anticorrosive property, and stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of deodorizing agent, which involves ultrasonically dispersing graphene oxide solution, adding chitosan, mixing, adding nano-titanium dioxide, polyvinylpyrrolidone, sodium bicarbonate, polyethylene glycol and water and filtering mixture.
