Abstract Covalent organic frameworks have received interest in many fields due to their fascinating properties. In this work, a flower-like covalent organic framework was prepared by a simple solvothermal method and used as an adsorbent for the removal of bisphenol A and 2,4-dichlorophenol from lake water. Due to the inherent hydrophobicity and large delocalized π-electron system, the proposed flower-like covalent organic framework forms π-π staking interactions with the aromatic ring-related compounds. Furthermore, the advantages of flower-like covalent organic framework, such as the porous structure and large specific surface area, facilitate the adsorption of phenolic compounds. Therefore, the flower-like covalent organic framework exhibited a relatively high affinity for bisphenol A and 2,4-dichlorophenol with adsorption capacity values of 56.8 mg/g and 36.6 mg/g, respectively. Furthermore, this material was successfully applied to remove bisphenol A and 2,4-dichlorophenol from lake water samples.

使用花状共价有机框架从湖水中去除双酚 A 和 2, 4-二氯苯酚

摘要 共价有机框架因其迷人的特性而在许多领域受到关注。在这项工作中，通过简单的溶剂热法制备了一种花状共价有机骨架，并将其用作吸附剂以去除湖水中的双酚 A 和 2,4-二氯苯酚。由于固有的疏水性和大的离域 π 电子系统，所提出的花状共价有机骨架与芳环相关化合物形成 π-π 桩相互作用。此外，花状共价有机骨架的多孔结构和大比表面积等优点有利于酚类化合物的吸附。因此，花状共价有机骨架对双酚 A 和 2,4-二氯苯酚表现出较高的亲和力，吸附容量值为 56。分别为 8 毫克/克和 36.6 毫克/克。此外，该材料已成功应用于去除湖水样品中的双酚 A 和 2,4-二氯苯酚。
