非水体系中大孔交联酰胺基树脂的吸附热力学
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.

Adsorption Thermodynamics of Macroporous Cross-linked Poly (N-methyl-N-p- vinylbenzylacetamine) Resin for Phenols from Non-aqueous System
Abstract:
The title resin was synthesized and the adsorption isotherms of phenol from cyclohexane solution were measured. Values of isosteric adsorption enthalpy, adsorption Gibbs free energy and adsorption entropy were calculated. These values implied a hydrogen-bonding adsorption mechanism. Furthermore, difference of adsorption property for phenol and o-nitrophenol from cyclohexane solution was studied, and the result was in accordance with the hydrogen-bonding mechanism.
