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．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.
