▎ 摘　　要

NOVELTY - Preparation of nano silver-loaded graphene-based composite adsorption material involves mixing a silver nitrate ethanol solution with concentration of 0.01-100 g/L, and a graphene oxide ethanol solution with concentration of 0.01-100 g/L, stirring, adding an artemisinin medicine, ultrasonically processing for 10-30 minutes, placing resultant product in UV lamp illumination for 30-60 minutes, washing with ethanol, centrifuging, and drying. The mass ratio of silver nitrate and graphene oxide is 1:1-1:50. USE - Preparation of nano silver-loaded graphene-based composite adsorption material used in sewage treatment and air purification. ADVANTAGE - The method enables simple and environmentally-friendly preparation of nano silver-loaded graphene-based composite adsorption material under mild reaction conditions, using wide source of raw materials.
