Environmental pollutants such as heavy metals,pesticides and veterinary drugs,dyes,etc.are toxic and non-degradable,which have great potential harm to the whole ecosystem and even human health and safety.As a new source of nanomaterials,plant biomass has been widely used in the preparation of nanomaterials because of its wide source,biodegradable and renewable characteristics,as well as rich pore structure and functional groups,which are capable of adsorbing some pollutants.In this paper,the various sources,classification and existing utilization technologies of plant biomass were briefly introduced,and the preparation and modification strategies of plant biomass nanomaterials were described.The latest research progress in the adsorption and removal of environmental pollutants was reviewed,and the application prospects of plant biomass nanomaterials were envisioned.
