▎ 摘 要
NOVELTY - Air purifier comprises 2-6% wt.% graphene, 1-3 wt.% calcium hypochlorite, 1-3 wt.% silver ion antibacterial liquid, 15-25 wt.% negative oxygen ion stock solution and remaining amount of water. USE - Used as an air purifier comprising graphene. ADVANTAGE - The air purifier has functions of sterilizing, removing formaldehyde and continuously releasing negative oxygen ions; is convenient use; and has wide application range and long action time. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparing air purifier comprising uniformly mixing graphene, calcium hypochlorite, silver ion antibacterial liquid, negative oxygen ion stock liquid and water to obtain the air purifying agent; and (2) use method of air purifier comprising applying air purifier to the surface of the object.
