| 摘 要： | 研究了活性炭对水中壬基酚聚氧乙烯醚(NP10EO)的吸附性能.吸附等温线结果表明,NP10EO的吸附量基本不受温度影响.动力学结果显示,NP10EO在活性炭上的吸附符合二级动力学,吸附速率受孔道内扩散控制;温度越高,NP10EO的速率常数越大.NP10EO在活性炭上的吸附是个吸热过程,活化能较小,主要为物理吸附过程.

| Abstract: | The adsorption of NP10EO onto actived carbon was investigated.The results of adsorption isotherm indicated that NP10EO adsorption was not influenced by temperature.The kinetics of NP10EO adsorption onto activated carbon could be well described by second order kinetics and the adsorption rate was dominated by intrapore diffusion process.Increasing temperature led to the increase of adsorption rate.The adsorption of NP10EO,which is an endothermic process,has a low energy of activation,and is mainly a physical... |
