| 摘 要： | 有效去除废水中苯胺及其衍生物是重要的环境问题. 由氯甲基聚苯乙烯树脂与丁二酰亚胺反应，合成大孔交联聚(对乙烯基苄基丁二酰亚胺)树脂(简称丁二酰亚胺树脂)，测定了丁二酰亚胺树脂对正庚烷溶液中苯胺的吸附性能. 结果表明:丁二酰亚胺树脂对正庚烷溶液中苯胺的吸附量大于原料树脂. 吸附等温线符合Freundlich等温吸附方程，相关系数大于0.99. 利用热力学函数计算了等量吸附焓变、吸附自由能变和吸附熵变. 树脂对正庚烷中苯胺的等量吸附焓变在20～30 kJ/mol，推测吸附过程为氢键吸附；同时，通过比较树脂对正庚烷溶液中苯胺和N,N-二甲基苯胺的吸附性能的差别，进一步论证了丁二酰亚胺树脂对正庚烷中苯胺的吸附是基于氢键作用的机理.

| Abstract: | Efficient removal of aniline and its derivatives from wastewater is of significant environmental concern.Macroporous cross-linked poly(p-vinylbenzyl succinimide) resin(succinimide resin) was synthesized by the reaction of chloromethylated polystyrene with succinimide,and the adsorption behaviors of the resin for aniline was also determined in heptane solution.The results indicated that the adsorption capacities of succinimide resin were higher than those of chloromethylated polystyrene resin for aniline in ... |
