摘 要: 本文主要研究的是碳纳米管对2，4-二氯苯酚的吸附性质，研究了时间、浓度、温度对吸附性能的影响，采用高效液相色谱法测定碳纳米管对2，4-二氯苯酚的吸附量，同时做了脱附研究。实验结果表明，时间、浓度、温度因素都对吸附有影响，随着吸附时间的延长，吸附量逐渐增加，直至达到最大吸附量，时间因素将不再影响吸附量。随着浓度的增大，吸附量将逐渐增大，呈线性趋势。随着温度的升高，吸附量有所下降。脱附试验使吸附物质得到浓缩，得到高浓度的2，4-二氯苯酚溶液。

Abstract: In the dissertation, we disclosed our research results on the adsorption and desorption of 2,4-dichlorophenol in the carbon nanotubes. In our research, we found adsorptive time, concentration of 2,4-dichlorophenol and temperature were main factors in adsorption. With the extension of adsorption, the absorptive proportion gradually increased until the maximum absorption capacity was obtained. The increasing of concentration of 2,4-dichlorophenol was in favor of the absorptive proportion. And as the temperature rising, the absorption proportion declined. We also explored desorption of 2,4-dichlorophenol in the carbon nanotubes in our research.
