摘要： 测定了不同温度下碳纳米管对水溶液中对硝基苯胺和N，N-二甲基苯胺的吸附等温线，探讨了其吸附热力学特性和机理.研究结果表明：在实验范围内，碳纳米管对两种化合物的吸附都能较好的符合Freundlich模型，两种物质的吸附都是放热和熵减小的自发过程；吸附过程均具有物理吸附特征.

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.
