| 摘 要： | 通过Friedel-Crafts后交联及化学修饰反应,合成了乙酰苯胺基修饰的超高交联吸附树脂ZH-05,通过红外光谱(IR)和比表面及孔径分析(BET)对其结构进行表征.以Amberlite XAD-4树脂作为参照,通过等温吸附实验和吸附动力学实验探讨了ZH-05树脂对水溶液中苯酚和对氯苯酚的吸附性能和机理.结果表明,与XAD-4树脂相比,ZH-05树脂对苯酚和对氯苯酚均具有更佳的吸附性能.Langmuir和Freundlich方程均能较好拟合ZH-05树脂对苯酚和对氯苯酚的吸附等温线.ZH-05树脂对苯酚和对氯苯酚的吸附以焓推动的自发物理吸附过程为主,吸附过程放热；吸附符合准一级动力学吸附方程,颗粒内扩散是吸附过程的主要控制步骤.

| Abstract: | The resin(named ZH-05) was prepared through the post-crossing of chloromethyl low crosslinking macroporous poly-styrene resin with acetylaniline and characterized by FT-IR and BET.The adsorption performance and mechanism for phenol and p-chlorophenol with ZH-05 were studied by static and kinetic adsorption experiments and adsorption capability of ZH-05 for phenol and p-chlorophenol were better than that of XAD-4.Langmuir and Freundlich isotherm equation can fit the adsorption isotherm of phenol and p-chlorophenol onto ZH-05 perfectly.Thermodynamics parameters showed that the adsorption was a mainly spontaneous physical adsorption process which driven by enthalpy and the process was exothermic.The pseudo-first-order kinetic adsorption equation can describe the adsorption dynamic behavior perfectly,which meant inner diffusion of the particles was the major controlling step of adsorption process. |
