摘　　要：利用1-萘甲酰氯、1-苯甲酰氯分别和β-环糊精反应制备萘、苯修饰的β-环糊精衍生物,再通过与十氟联苯进行缩合反应生成萘、苯修饰的β-环糊精凝胶(DFB-N-CD、DFB-B-CD),研究了两种环糊精凝胶对有机污染物双酚A(BPA)的吸附性能。结果表明,萘、苯基团能够和水中的BPA通过π-π相互作用进行结合,从而提升了改性环糊精凝胶对于BPA的吸附量和选择特异性。其中,DFB-B-CD对BPA的吸附效果最好,吸附量能够达到613.29 mg·g^(-1),并且其在5次循环利用后对BPA仍能保持较高的去除率(可达81.39%)。这种通过π-π相互作用增强对BPA污染物吸附容量的方法,为推动β-环糊精凝胶在水处理方面的应用提供了新的思路。Naphthalene and benzene modifiedβ-cyclodextrin derivatives were prepared by reactions between 1-naphthoyl chloride,1-benzoyl chloride andβ-cyclodextrin,respectively.The two reaction products were condensed with decafluorobiphenyl to form naphthalene and benzene modified cyclodextrin gels(DFB-N-CD,DFB-B-CD).The adsorption properties of two cyclodextrin gels to organic pollutants bisphenol A(BPA)were studied.The results show that the naphthalene and benzene groups can be combined with BPA in water byπ-πinteraction,thus enhancing the adsorption and selective specificity of modified cyclodextrin gel for BPA.Among them,DFB-B-CD has the best adsorption effect on BPA,the adsorption capacity can reach 613.29 mg·g^(-1),and it can still maintain a high removal rate of BPA(up to 81.39%)after five cycles.This method of enhancing the adsorption capacity of BPA pollutants throughπ-πinteraction provides new ideas for promoting the application ofβ-Cyclodextrin gel in water treatment.
