简述了碳纳米管的结构、性质及优异的吸附性能，介绍了碳纳米管的表面改性方法，总结了对不同目标物吸附效果的差异。表面改性有利于碳纳米管对水中重金属离子的吸附，对不同的有机污染物而言，不同的修饰官能团的吸附效果差异较大。指出了吸附竞争和提高选择性等是未来需要研究的方向。

The structure and properties of carbon nanotubes (CNTs) were presented briefly. CNTs had excellent adsorption capacity, but the adsorption of pollutants in wastewater was limited. The surface modifications of CNTs such as covalent modification, non-co-valent modification and modification using low temperature plasma were introduced. The differences in adsorption effect on different pollutants were summarized. Surface modification was advantageous to adsorption capacity on metals ions in water. The adsorption effect of various modified functional groups on organic pollutants was different. It was pointed out that the adsorption competition and improve the selectivity were ways to the future.
