| 摘 要： | 碳纳米管具有独特的物理化学特性,对污染物具有优异的吸附性能,在环保领域具有巨大的应用潜力,因而吸引人们对碳纳米管吸附有毒污染物的行为和规律开展了大量研究.同时,碳纳米管特有的表面化学性质和结构特征,使得其自身的环境行为具有一定的风险性,对碳纳米管在水土环境中的迁移行为进行评价,是碳纳米管工程应用之前必须要解决的重要问题,相关研究也有一定程度的开展.本文从碳纳米管对环境污染物的吸附行为和相关机理以及碳纳米管在水土环境中的迁移行为方面进行了综述,阐述了这些研究对于评估碳纳米管的环境应用潜力、环境和生态风险所具有的意义.

| Abstract: | The widespread uses and applications of cabon nanotubes ( CNTs) along with the lack of regulations for disposal leave a gap for possible release into the environment Hence, the transport and the fate of CNTs in the water and soil environments are the subjects of numerous studies.This review summarizes the progress in the adsorption of heavy metals and organic chemicals onto CNTs as well as the transport of CNTs in the water and soil environments.Adsorption and transport mechanisms as affected by the surface properties of CNTs, physics-chemical properties of adsorbates, and the environmental conditions are discussed. |
