| 摘 要： | 合成了大孔交联聚（N-甲基-N-对乙烯基苄基乙酰胺）树脂,测定了树脂对环己烷溶液中苯酚的吸附等温线,根据热力学函数关系计算了等量吸附焓、吉布斯吸附自由能和吸附熵,推测吸附过程为氢键吸附.同时,通过比较树脂对环己烷溶液中苯酚和邻硝基苯酚的吸附性能的差别,进一步论证了大孔交联聚（N-甲基-N-对乙烯基苄基乙酰胺）树脂对非水体系中酚类物质的吸附是基于氢键作用的机理.

| Abstract: | The title resin was synthesized and the adsorption isotherms of pheno l from cyclohexane solution were measured.Values of isosteric adsorption enthalp y,adsorption Gibbs free energy and adsorption entropy were calculated.These valu es implied a hydrogen-bonding adsorption mechanism.Furthermore,difference of ad sorption property for phenol and o-nitrophenol from cyclohexane solution was st udied,and the result was in accordance with the hydrogen-bonding mechanism. |

| Keywords: | Macroporous cross-linked poly(N-methyl-N-p-vinylbenzylacetamine ) resin Non-aqueous system Phenols Hydrogen-bonding Adsorption mechanism |
