碳纳米管（CTN）对水中铅的吸附表现出优异的吸附性能和较高的吸附效率。溶液的pH值和纳米管的表面状态对吸附有显著的影响，这可以通过它们的处理工艺来控制。吸附等温线均符合Langmuir和Freundlich吸附模型，表明碳纳米管是一种良好的Pb2+吸附剂，在环境保护方面具有巨大的应用潜力。(C)2002 Elsevier Science B.V.保留所有权利。
Carbon nanotubes (CTNs) show exceptional adsorption capability and high adsorption efficiency for lead removal from water. The adsorption is significantly influenced by the pH value of the solution and the nanotube surface status, which can be controlled by their treatment processing. The adsorption isotherms are well described by both Langmuir and Freundlich models, Our results suggest that CNTs can be good Pb2+ adsorbers and have great potential applications in environmental protection.
