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.展开更多
