摘要：以 β-环糊精为原料，环氧氯丙烷为交联剂，在碱性条件下合成 β-环糊精/环氧氯丙烷共聚物（β-CDP），
并将其用于吸附水溶液中的双酚酸（DPA）。考察了 pH 及 β-CDP 与 DPA 的质量比对吸附的影响。结果表明：
当 pH≤4.3 时，有利于 β-CDP 对 DPA 的吸附，且当 β-CDP 与 DPA 的质量比为 12.5∶1 时，β-CDP 对 DPA 的吸
附性能最佳，此时的平衡吸附量为 63.7 mg/g。分析了 β-CDP 吸附 DPA 的机理：β-CDP 对 DPA 的吸附速率很快，
吸附过程主要受氢键和疏水作用影响，吸附符合准二级动力学模型，可用 Langmuir 和 Freundlich 吸附等温模型
描述。β-CDP 对 DPA 的吸附具有热力学可行性和自发性，吸附过程放出热量。β-CDP 再生性能良好，经过 5 次
吸附-解吸循环实验，每次 β-CDP 均能保持 90%的吸附性能。

Abstract: β-Cyclodextrin/epichlorohydrin copolymer (β-CDP) was synthesized in alkaline medium using
β-cyclodextrin as monomer and epichlorohydrin as crosslinker and used as adsorbent for the adsorption of
diphenolic acid (DPA) from the water solution. The influences of pH and mass ratio of β-CDP to DPA on
the DPA adsorption were investigated. The results showed that the adsorption efficiency for DPA was fairly
good when the pH was less than 4.3 and the equilibrium adsorption capacity was 63.7 mg/g when the mass
ratio of β-CDP to DPA was 12.5∶1. At the same time, the adsorption mechanism of β-CDP for DPA was
discussed. A rapid adsorption rate for the removal of DPA onto β-CDP from water solution was achieved,
and the adsorption process was mainly due to hydrogen bond and hydrophobic interaction. The adsorption
kinetics agreed with the pseudo second-order kinetic model. The isothermal adsorption process was well
described by Langmuir and Freundlich models. The thermodynamic study revealed that the adsorption
process was spontaneous and exothermic in nature. The β-CDP had good regeneration performance,
especially the adsorption capacity of β-CDP remained 90% of the initial adsorption capacity for DPA after
five cycles of adsorption-desorption.
