| 摘 要： | 测定D301树脂对环己烷溶液中苯酚的吸附等温线，利用热力学函数关系计算了等量吸附焓，吸附自由能和吸附熵，等量吸附焓在30kJ/mol-35kJ/mol之间，推测吸附过程为氢键吸附。比较D301树脂对水溶液和环己烷溶液中苯酚的吸附性能，及D301树脂对环己烷溶液中苯酚和邻硝苯酚的吸附性能，进一步讨论了D301树脂对酚类物质吸附中的氢键作用。 |

| Abstract: | Adsorption isotherms of phenol onto D301 resin from cyclohexane solution were measured. Isosteric adsorption enthalpy, adsorption free energy and adsorption entropy were calculated according to the relationship of thermodynamic function. Isosteric adsorption enthalpy was between 30kJ/mol and 35kJ/mol, which reveals a hydrogen-bonding adsorption mechanism. Difference of adsorption property of phenol onto D301 resin from aqueous solution and cyclohexane solution, and that of phenol and o-nitrophenol from cyclohexane solution were studied, and the results show the hydrogen-bonding based adsorption for phenols from non-aqueous solution furthermore. |
| Keywords: | D301 resin Cyclohexane Phenol o-Nitrophenol Hydrogen-bonding Adsorption thermodynamics |
