摘　　要：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 betacyclodextrin-based adsorbents.The beta-cyclodextrin/chitosan functionalized graphene oxide hydrogel with specific surface of 17.6 m^(2)·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,costeffective analysis,challenges,and future directions of betacyclodextrin-based adsorbents in wastewater treatment.
