Adsorption and separation materials made from raw material of cellulose can reduce the use of petroleum resources and has many advantages such as low cost

environmentally friendly and good biocompatibility. Cellulose contains large amounts of hydroxyl groups which can be modified by the reaction of crosslinking

grafting

introducing inorganic particles or combination with polymer to prepare adsorption and separation materials with the morphology of microsphere or film. These materials are widely used in biomedical

waste water treatment

gas separation and other fields. In this paper

the latest advances on research of cellulose and its composite materials in adsorption and separation fields of water

oil

heavy metal ions

gases and organics were reviewed by summarizing the relevant papers published during the past 5 years. Based on this

the research trend and the existing problems were discussed.
