A nucleophilic substitution reaction to crosslink cyclodextrin (CD) polymer with rigid aromatic groups, providing a high surface area, mesoporous CD-containing polymers (P-CDPs). The P-CDPs can be used for removing organic contaminants from water. By encapsulating pollutants to form well-defined host-guest complexes with complementary selectivities to activated carbon (AC) sorbents. The P-CDPs can rapidly sequester pharmaceuticals, pesticides, and other organic micropollutants, achieving equilibrium binding capacity in seconds with adsorption rate constants 15-200 times greater than ACs and nonporous CD sorbents. The CD polymer can be regenerated several times, through a room temperature washing procedure, with no loss in performance.
通过亲核取代反应,环糊精(CD)聚合物与刚性芳香基团发生交联,从而形成高比表面积的介孔含 CD 聚合物(P-CDPs)。P-CDPs 可用于去除水中的有机污染物。通过封装污染物,形成与活性炭(AC)吸附剂具有互补选择性的定义明确的主客复合物。P-CDPs 可以快速吸附药物、农药和其他有机微污染物,在几秒钟内就能达到平衡吸附容量,吸附速率常数比 AC 和无孔 CD 吸附剂高 15-200 倍。CD 聚合物可通过室温洗涤程序再生多次,而性能不会降低。
