| 摘 要： | 利用新型磺酸基修饰复合功能树脂NG-6对水中对氨基苯酚进行吸附,深入探讨了吸附中的动力学及热力学行为.实验结果表明,对氨基苯酚在NG-6上的吸附能够在较短的时间内达到平衡,动力学特性符合准二级动力学方程.此吸附是一个放热的自发过程,Freundlich等温吸附方程能够较好地拟合吸附等温线. |

| Abstract: | In this study,a hydrophilic bifunctional resin(NG-6) with sulfonic groups was synthesized.And the study on the adsorption kinetics and thermodynamics of p-aminophenol onto NG-6 were carried out.The experimental results indicate that the adsorption would attain the equilibrium in a short time and obeys the pseudo-second order rate equation.All the isothermal data fit well to the Freundlich model.The values of adsorption enthalpy change are all negative,which indicates that the adsorptions are exothermic processes.In addition,the negative free energy change values show that all these adsorption processes are spontaneous. |
