Abstract: The thermodynamic characteristics and mechanism of 4-nitroaniline and N,N-dimethylaniline adsorption by carbon nanotubes were studied and the adsorption isotherm line at different temperature were determined . The results showed that the adsorption of 4-nitroaniline and N,N-dimethylaniline accorded with Freundlich model well and that the adsorption is spontaneous , exothermic and decreasing entropy process. The process is physical adsorption.

Key words: 4-nitroaniline, N, N-dimethylaniline, adsorption, mechanism, thermodynamics, carbon nanotubes, 4-nitroaniline, N, N-dimethylaniline, adsorption, mechanism, thermodynamics
