摘　　要：新污染物具有毒性、环境持久性、生物累积性等特点,近几年在水中被频繁检测出,对人类健康和生态环境造成潜在威胁,如何去除水中新污染物是当前的研究热点。研究发现,纳米纤维素基吸附材料在新污染物的处理中有很好的吸附效果。文中介绍了纳米纤维素的类别、制备及改性方法,综述了纳米纤维素基材料对水中持久性有机污染物、内分泌干扰物、抗生素及微塑料的去除应用,并提出了今后的研究要点应为不同类型新污染物同时高效地吸附,及吸附后的处理和再生问题。New pollutants are toxic,persistent and bioaccumulation,and have been detected frequently in water in recent years,posing potential threats to human health and the ecological environment,how to remove the new pollutants in water is the current research hotspot.It is found that the nano-cellulose-based adsorbent has good adsorption effect in the treatment of new pollutants.The types,preparation and modification methods of nano-cellulose were introduced,and the removal of Persistent organic pollutant,endocrine disruptors,antibiotics and microplastics by nano-cellulose-based materials was reviewed,it was also pointed out that the key points of future research should be the simultaneous and efficient adsorption of different types of new pollutants,and the treatment and regeneration after adsorption.
