摘　　要：以纤维素为原料制备吸附分离材料可以减少对石油资源的依赖,并具有成本低、环境友好和生物相容性好等优点。利用纤维素中的羟基基团,通过交联、接枝、引入无机粒子或与聚合物复合,可以制备出微球和薄膜等不同形态的吸附分离材料,广泛应用于生物医学,废水处理、气体分离等领域。本文结合近五年来国内外纤维素及其复合材料在吸附分离领域的研究近况,从水、油、重金属、气体和有机物的应用进行了综述,总结了纤维素基吸附分离材料的研究尚存在的问题,探讨了今后的研究方向。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 5years.Based on this,the research trend and the existing problems were discussed.
