Starch is one of the most abundant polysaccharides in nature and has a high potential for application in several fields, including effluent treatment as an adsorbent. Starch has a unique structure, with zones of different crystallinity and a glycosidic structure containing hydroxyl groups. This configuration allows a wide range of interactions with pollutants of different degrees of hydrophilicity, which includes from hydrogen bonding to hydrophobic interactions. This review article aims to survey the use of starch in the synthesis of diverse adsorbents, in forms from nanoparticles to blends, and evaluates their performance in terms of amount of pollutant adsorbed and removal efficiency. A critical analysis of the materials developed, and the results obtained is also presented. Finally, the review provides an outlook on how this polysaccharide can be used more effectively and efficiently in remediation efforts in the near future.
淀粉是自然界中最丰富的多糖之一，在包括作为吸附剂用于污水处理等多个领域具有很高的应用潜力。淀粉具有独特的结构，有不同结晶度区域以及含有羟基的糖苷结构。这种构型使得它能够与不同亲水性程度的污染物发生广泛的相互作用，包括从氢键到疏水相互作用。这篇综述文章旨在调查淀粉在合成各种吸附剂中的应用，从纳米颗粒到共混物等形式，并根据吸附的污染物量和去除效率评估它们的性能。还对所开发的材料和获得的结果进行了批判性分析。最后，该综述展望了这种多糖在不久的将来如何能更有效且高效地用于修复工作。
