| 摘 要： | 将D301树脂的叔胺基氧化，合成了大孔交联氧化叔胺树脂．比较D301树脂与氧化叔胺树脂对正己烷溶液中和水溶液苯酚的吸附性能，发现氧化叔胺树脂对苯酚的吸附量比D301树脂的有明显的增加．为弄清吸附量增加的原因，根据氧化叔胺树脂对正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Gibbs自由能和吸附熵，发现叔胺树脂氧化后，与苯酚的相互作用和吸附的自发倾向增强，但吸附过程仍为氢键吸附．

| Abstract: | The title resin was synthesized by oxidation of D301 resin. Adsorption properties for phenol in hexane and aqueous solution of the oxidized tertamine resin were compared with those of D301 resin, and the result showed that adsorption capacities of the oxidized tertamine resin were larger than those of D301 resin both in hexane and in aqueous solution. In order to rationalize the enhancement of adsorption capacity, values of isosteric adsorption enthalpy, adsorption Gibbs free energy and adsorption entropy were calculated from the isotherms of phenol adsorbed onto the oxidized tertamine resin in hexane solution according to thermodynamic function relationships. The results showed that the interactions between the oxidized resin and phenol were stronger than those between D301 resin and phenol, and the adsorption feasibility for phenol was enhanced as the oxidation of the resin, and yet adsorption of phenol onto the oxidized resin in hexane was also based on hydrogen bonding. |
