-
The adsorption of aniline on the as-grown and purified carbon nanotubes has been investigated.The initial concentration of aniline solution,time,temperature and pH values of aniline solution have great influence on the adsorption capacity.The adsorption capacity of the as-grown carbon nanotubes towards aniline was 4.8 mg/g at pH=5.For that treated with nitric acid,it increased to 15.4 mg/g.The adsorption capacity decreased with increase of temperature in the range of 283 to 303 K.The adsorption isotherms can be described by Freundlich equation.
