▎ 摘　　要

NOVELTY - An attapulgite-based purifying adsorbent is prepared by mixing silver nitrate, graphene oxide and reducing agent in reaction kettle with water, hydrothermally reacting to obtain reduced graphene oxide solution loaded with nano-silver, filtering to obtain nano-silver-reduced graphene oxide, dispersing in solvent, adding attapulgite, stirring and reacting. USE - The method is used for preparing attapulgite-based purifying adsorbent. ADVANTAGE - The method uses silver and reduced graphene oxide as sterilizing material that are simultaneously reduced to integral structure and loaded on attapulgite, and improves sterilization effect on harmful bacteria in air.
