▎ 摘  要

NOVELTY - Adsorbent comprises 28-32 pts. wt. zinc oxide modified active carbon, 24-27 pts. wt. modified attapulgite, 16-18 pts. wt. oxidized graphene, 19-22 pts. wt. sodium humate, 7-8 pts. wt. nano manganese dioxide, 2-4 pts. wt. nano cerium oxide, 3-5 pts. wt. nano aluminum nitride and 1.5-2.5 pts. wt. 2-amino-2-ethyl-1,3-propylene glycol. USE - The adsorbent is useful for air purification (claimed). ADVANTAGE - The adsorbent has wide application range, is safe and environmentally-friendly, is convenient to use, and has high adsorption capacity. The method is simple and easy to operate. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a preparation method of adsorbent for air purification comprising (i) crushing zinc oxide modified active carbon, modified attapulgite, sodium humate and 2-amino-2-ethyl-1,3-propylene glycol by 300-mesh sieve, and uniformly mixing at 45-50℃, and (ii) adding oxidation graphene nano manganese dioxide, nano aluminum nitride, nano cerium oxide and water into the mixture to granulate, granulating, and drying at room temperature to obtain adsorbent for air purification.
