| 摘 要： | 由氯甲基化聚苯乙烯合成了大孔交联聚(对乙烯基苄基苯胺)树脂, 测定了其对正己烷和水中苯酚的吸附等温线, 计算了吸附焓. 结果表明, 苯胺基树脂主要是通过氢键吸附正己烷中苯酚的, 树脂负载的功能基氮原子和苯环都作为氢键受体与苯酚的羟基氢原子形成氢键, 而其对水中苯酚的吸附是基于氢键和疏水作用.

| Abstract: | Macroporous crosslinked poly(p-vinylbenzylaniline) resin was synthesized from chloromethylated polystyrene, and the adsorption isotherms of phenol in hexane and in aqueous media were measured, and adsorption enthalpies were calculated. The results indicated that hydrogen bonding was primarily responsible for the adsorption in hexane, and the nitrogen atom and benzene ring of the loaded aniline group of the resin acted as hydrogen bonding acceptors to form hydrogen bonding with the hydrogen atoms of the hydroxyl groups of phenols, while hydrogen bonding and hydrophobic interaction were involved for the adsorption in aqueous media. |
