Separation and pre-concentration of trace pollutants from their matrix by reversible formation of inclusion complexes has turned into a widely studied field, especially for the benefits provided to different areas. Cyclodextrins are non-toxic oligosaccharides that are well known for their host-guest chemistry, low prices, and negligible environmental impact. Therefore, they have been widely used as chiral selectors and delivery systems in the pharmaceutical and food industry over time. However, their use for extraction purposes is hampered by their high solubility in water. This difficulty is being overcome with a variety of investigations in materials science. The setting-up of novel solid sorbents with improved properties thanks to the presence of cyclodextrins at their structure is still an open research area. Some properties they can offer, such as an increased selectivity or a good distribution along the surface of a solid support, which provides better accessibility for guest molecules, are characteristics of great interest. This systematic review reports the most significant uses of cyclodextrins for the adsorption of pollutants in different-origin samples based on the works reported in the literature in the last years. The study has been carried out indistinctly for quantitation and remediation purposes.
通过形成包合物可逆地从其基质中分离和预富集痕量污染物已成为一个广泛研究的领域，特别是因其为不同领域带来的益处。环糊精是无毒的寡糖，以其主客体化学、低价格和可忽略不计的环境影响而闻名。因此，随着时间的推移，它们在制药和食品工业中被广泛用作手性选择剂和递送系统。然而，它们在水中的高溶解度阻碍了其用于萃取目的。材料科学领域的各种研究正在克服这一困难。由于环糊精存在于其结构中而具有改进性能的新型固体吸附剂的开发仍然是一个开放的研究领域。它们可以提供的一些特性，例如增加的选择性或沿固体载体表面的良好分布，这为客体分子提供了更好的可及性，是非常令人感兴趣的特性。本系统综述基于过去几年文献报道的工作，报告了环糊精在不同来源样品中吸附污染物的最重要用途。该研究已不分定量和修复目的进行。
