▎ 摘　　要

NOVELTY - Preparation of fluorescence adsorption material loaded with graphene quantum dot comprises adjusting pH of nitrogen-doped quantum dot solution to 7.0, obtaining quantum dot solution (NGODs ), and adjusting pH value; and mixing polyvinyl alcohol solution and NGODs solution, obtaining mixed solution, adding citric acid solution into mixed solution, carrying out crosslinking reaction to obtain product solution, drying and curing product solution. USE - The method is used for preparing fluorescence adsorption material loaded with graphene quantum dot. ADVANTAGE - The material has high selective adsorption effect to silver. The fluorescence intensity will be obviously generated after absorbing silver.
