Abstract In this study, 4,4′-(hexafluoroisopropene) diphthalic acid (PDA)-CD polymers containing β-cyclodextrin (CD) were synthesized for the adsorption of endocrine disrupting chemicals (EDCs) and dyes. It features great adsorption of bisphenol A (BPA), methylene blue (MB) and neutral red (NR). The maximum adsorption capacities of MB, NR and BPA can reach 113.06, 106.8 and 51.74 mg/g, respectively. The tandem adsorption results revealed that adsorptions of dyes and BPA onto PDA-CD polymer were two independent processes: non-polar BPA entrapment by cyclodextrin cavities while dyes were captured by the carboxyl groups and π-π stacking interactions. The adsorption processes performed well in a wide range of pH (4.0–10.0) and were not affected by fulvic acid (FA) and inorganic ions.

PDA 交联 β-环糊精：一种用于去除 BPA 和阳离子染料的新型吸附剂

摘要在这项研究中，合成了含有β-环糊精（CD）的4,4'-（六氟异丙烯）二邻苯二甲酸（PDA）-CD聚合物，用于吸附内分泌干扰化学品（EDC）和染料。它对双酚A（BPA）、亚甲基蓝（MB）和中性红（NR）具有良好的吸附能力。MB、NR和BPA的最大吸附量分别达到113.06、106.8和51.74 mg/g。串联吸附结果表明，染料和 BPA 在 PDA-CD 聚合物上的吸附是两个独立的过程：环糊精空腔对非极性 BPA 的捕获，而染料被羧基和 π-π 堆积相互作用捕获。吸附过程在较宽的pH范围（4.0-10.0）下表现良好，并且不受黄腐酸（FA）和无机离子的影响。
