This short review aims to critically discuss the recent advances in supramolecular chemistry to achieve the aggregation of nanoplastics in aquatic systems. Polymer modification provides a vital tool for designing novel and ad hoc synthesized surfactants with properties tuned for some specific applications (e.g., stimuli-responsive nanomaterial, conducting polymers), mainly to aggregate other polymers from the environment. Far from the typical use of surfactants, which ease the dispersion of insoluble molecules in water media or aid solubilization of insoluble molecules on local media, in this case, nanoarchitectonics serve researchers to design surfactants with a focus on the capture of nanoplastics from the environment. Additionally, monovalent and divalent salt additions aided NPs in coagulating in the aquatic systems. Finally, the latest research on NPs' removal efficiency on wastewater treatment plant is reviewed to summarize the advances.
这篇简短的综述旨在批判性地讨论超分子化学在实现水生系统中纳米塑料聚集方面的最新进展。聚合物改性为设计具有针对某些特定应用(如刺激响应纳米材料、导电聚合物)进行性能调整的新型和特制合成表面活性剂提供了重要工具,主要用于聚集来自环境中的其他聚合物。与表面活性剂的典型用途不同,表面活性剂可使不溶性分子在水介质中分散或有助于不溶性分子在局部介质中溶解,在这种情况下,纳米结构有助于研究人员设计专注于从环境中捕获纳米塑料的表面活性剂。此外,添加一价和二价盐有助于纳米颗粒在水生系统中凝聚。最后,综述了关于纳米颗粒在废水处理厂去除效率的最新研究,以总结进展情况。
