▎ 摘　　要

NOVELTY - Preparing chitosan modified graphene oxide quantum dots adsorbent material involves dissolving chitosan in 4 wt.% acetic acid solution and sonicating at 100W for 30 minutes. Crosslinking agent and quantum dot graphene oxide are added in solution of chitosan in acetic acid and treated at room temperature with magnetic stirring for 60-90 minutes. After adjustment of pH of mixed solution, magnetic stirring is continued for 1 hour. Resulting mixture is washed with water, ethanol and repeatedly washed until neutral and dried to obtain chitosan modified graphene oxide quantum dot adsorbent material. USE - Method for preparing chitosan modified graphene oxide quantum dots adsorbent material (claimed) used in water pollution treatment and biomedicine. ADVANTAGE - The method enables to prepare chitosan modified graphene oxide quantum dots adsorbent material, which is prepared simple process with easily available raw materials, mild conditions, where resulting adsorbent has good adsorption properties.
