Abstract: Cellulose materials as a novel class of adsorbents,  it has excellent mechanical properties and chemical stability,   their adsorption performance can be significantly enhanced through chemical modification. In the context of removing pollutants from aqueous solutions,  cellulose materials show good adsorption capabilities for contaminants such as heavy metal ions,  organic small molecules,  and microplastics,   they can also be used as  blood purification adsorbent for the treatment of blood-related diseases. We review the application of cellulose materials in the purification of aqueous solutions,   and  summarize the research process of cellulose materials as adsorbents.

Key words: cellulose,  , chemical modification,  , water purification,  , blood purification
