含β-环糊精（β-CD）的大孔多胺用于从水溶液中回收各种有机污染物。合成了几种不同β-CD度的不溶性多胺。本文对吸附动力学、污染物浓度、溶液pH值和β-CD含量的影响进行了研究。吸附实验结果表明，这些吸附剂对取代酚类衍生物表现出较高的吸附容量。吸附机制是通过酸碱相互作用、离子交换和氨基引起的氢键作用在树脂聚合物网络中的物理吸附，以及β-CD分子通过主客体相互作用和疏水相互作用（如主客体相互作用）形成包合物。© 1999 John Wiley & Sons，Inc.应用聚合物科学杂志73：2903-2910，1999
Macroporous polyamines containing β-cyclodextrin (β-CD) are used for the recovery of various organic pollutants from aqueous solutions. Several insoluble polyamines with various degrees of β-CD were prepared. Studies concerning the sorption kinetics, the effect of pollutant concentration, pH of the solutions, and β-CD content are presented here. The results of sorption experiments show that these sorbents exhibit high sorption capacities toward substituted phenolic derivatives. The mechanism of sorption is both physical adsorption in the resin polymer network through acid–base interactions, ion exchange, and hydrogen bonding due to the amino groups and the formation of an inclusion complex due to the β-CD molecules through host–guest interactions, and hydrophobic interactions such as guest–guest interactions. © 1999 John Wiley & Sons, Inc.
