Beta-cyclodextrin-based adsorbent is a promising adsorbent because it has unique characteristics and able to form host-guest complexes with various organic compounds. Adsorption using beta-cyclodextrin-based adsorbent has continuously improved by various preparation strategies and crosslinking agents. This commentary aims to highlight the preparation strategies, properties, and adsorption mechanisms of beta-cyclodextrin-based adsorbents. The adsorbents can be generally classified according to the preparation methods and display high adsorption capacity especially for dyes. Particularly, composite/nanocomposite beta-cyclodextrin-based adsorbents exhibit outstanding adsorption capacity even though the surface area is lower than that of porous and magnetic beta-cyclodextrin-based adsorbents. The beta-cyclodextrin/chitosan functionalized graphene oxide hydrogel with specific surface of 17.6 m²·g⁻¹ yields an extraordinarily maximum adsorption capacity of 1499 mg·g⁻¹ methylene blue, while beta-cyclodextrin/chitosan modified with iron(II, III) oxide nanoparticles displays a much greater maximum adsorption capacity at 2780 mg·g⁻¹. The hydrophobic interaction, functional groups, hydrogen bonding, and electrostatic interaction govern the adsorption to a greater capacity. Although this commentary is not exhaustive, the preparation strategies and illustrated mechanisms provide useful insights into the adsorbent-adsorbate interactions, cost-effective analysis, challenges, and future directions of beta-cyclodextrin-based adsorbents in wastewater treatment.

β-环糊精基吸附剂是一种很有前途的吸附剂，因为它具有独特的特性，能够与各种有机化合物形成主客体复合物。使用基于 β-环糊精的吸附剂的吸附通过各种制备策略和交联剂不断改进。本评论旨在强调基于 β-环糊精的吸附剂的制备策略、性质和吸附机制。吸附剂一般可按制备方法分类，吸附能力强，特别是对染料吸附能力强。特别是，复合/纳米复合β-环糊精基吸附剂表现出出色的吸附能力，即使表面积低于多孔和磁性β-环糊精基吸附剂。² ·g ^-1的最大吸附量为 1499 mg·g ^-1亚甲蓝，而用氧化铁 (II, III) 纳米粒子改性的 β-环糊精/壳聚糖在 2780 mg·g - 时表现出更大的最大吸附量^{- 1} . 疏水相互作用、官能团、氢键和静电相互作用将吸附控制到更大的容量。虽然这篇评论并不详尽，但制备策略和说明的机制为废水处理中基于 β-环糊精的吸附剂的吸附剂-吸附质相互作用、成本效益分析、挑战和未来方向提供了有用的见解。
