| 摘 要： | 实验研究了四溴双酚A生产废水中的氯苯在苯乙烯型大孔树脂上的吸附行为,考察了氯苯初始浓度、溶液pH值及温度对吸附性能的影响;探讨吸附氯苯的动力学过程,测定了氯苯在不同温度下的吸附等温线.结果表明:吸附过程符合Freundlich吸附模型,吸附过程符合拟二级动力学模型,其相关系数大于0.99;在温度283 K、pH值为1.0～2.0、氯苯溶液质量浓度为6 612 mg/L条件下,树脂饱和吸附量为267.8 mg/g.

| Abstract: | The adsorption behavior for chlorobenzene from TBBP-A by polymeric macroporous resin was studied.The influences of the initial chlorobenzene concentration,pH and temperature on the adsorption performance were discussed,and the kinetics of chlorobenzene adsorption was explored,and the adsorption isotherms of chlorobenzene at different temperature were measured.The results indicate that the adsorption isotherm of chlorobenzene fits well into the Freundlich adsorption isotherm,and the adsorption kinetic data fits to the pseudo-second-order model;the chlorobenzene adsorption capacity of resin is 267.8 mg/g when chlorobenzene concentration is 6 612 mg/L and pH value is 1-2 at 283 K. |
