摘　　要：Purification processing has a great effect on carbon nanotubes.On one hand it can remove impurities and increase the surface area of carbon nanotubes.On the other hand it can introduce functional groups such as hydroxyl,carboxyl and carbonyl on the surface of carbon nanotubes.Both improved the adsorption capability of carbon nanotubes.The adsorption processes can be well modeled by isothermic equation Freundlich and equation de Boer-Ziwkker.The results also showed that carbon nanotubes can be regenerated and have great potential applications in environmental protection.Purification processing has a great effect on carbon nanotubes.On one hand it can remove impurities and increase the surface area of carbon nanotubes.On the other hand it can introduce functional groups such as hydroxyl,carboxyl and carbonyl on the surface of carbon nanotubes.Both improved the adsorption capability of carbon nanotubes.The adsorption processes can be well modeled by isothermic equation Freundlich and equation de Boer-Ziwkker.The results also showed that carbon nanotubes can be regenerated and have great potential applications in environmental protection.
