Water pollution, which has become a global problem in parallel with environmental pollution, is a problem that needs to be solved urgently, considering the gradual depletion of water resources. The inadequacy of the water treatment methods and the materials used somehow directed the researchers to look for dual character structures such as biocompatible and biodegradable β-cyclodextrin (β-CD). β-CD, which is normally insoluble in water, is used in demanding wastewater applications by being modified with the help of different agents to be water soluble or transformed into polymeric adsorbents as a result of co-polymerization via cross-linkers. In this way, in addition to the host-guest interactions offered by β-CD, secondary forces arising from these interactions provide advantages in terms of regeneration and reusability. However, the adsorption efficiency and synthesis steps need to be improved. Based on the current studies presented in this review, in which cross-linkers and modification methods are also mentioned, suggestions for novel synthesis methods of new-generation β-CD-based materials, criticisms, and recent methods of removal of micropollutants such as heavy metals, industrial dyes, harmful biomolecules, and pharmaceutics wastes are mentioned.
水污染与环境污染同步成为一个全球性问题，鉴于水资源的逐渐枯竭，这是一个亟待解决的问题。水处理方法和所使用材料的不足在某种程度上促使研究人员去寻找具有双重特性的结构，比如生物相容性和可生物降解的β-环糊精（β-CD）。β-CD通常不溶于水，通过借助不同试剂进行改性使其具有水溶性，或者通过交联剂进行共聚转化为聚合物吸附剂，从而用于要求苛刻的废水处理应用中。这样一来，除了β-CD提供的主客体相互作用外，这些相互作用产生的次级作用力在再生和可重复使用方面具有优势。然而，吸附效率和合成步骤仍需改进。基于本综述中呈现的当前研究（其中也提到了交联剂和改性方法），提到了关于新一代β-CD基材料新型合成方法的建议、批评意见以及去除重金属、工业染料、有害生物分子和制药废物等微污染物的最新方法。
