Abstract

The widespread presence of diuretics in wastewater, driven by their growing use in managing hypertension, heart failure, and kidney disorders as well as their chemical stability and bioactivity, poses significant environmental risks. To address these limitations, we developed a host–guest interaction-driven sandwich-like nanocomposite membrane with alternating porous and fibrous layers for rapid diuretic removal. The HPβCD composite membrane (HPβCD CM) demonstrated stable adsorption performance under acid and alkaline conditions. Within 60 s, the HPβCD CM achieved >70% removal of hydrochlorothiazide, exhibiting an adsorption rate constant 2–3 times higher than those of GAC and single-component β-cyclodextrin polymers. The maximum adsorption capacities of the membrane reached 300 mg/g for HCTZ and 200 mg/g for bendroflumethiazide and indapamide. With its outstanding adsorption performance, cost-effectiveness, and ease of regeneration, the HPβCD CM represents a promising solution for advanced water treatment applications.

主客体驱动的三明治状环糊精膜在废水中利尿剂的瞬时吸附

由于利尿剂在高血压、心力衰竭和肾脏疾病的治疗中越来越多地使用，以及它们的化学稳定性和生物活性，利尿剂在废水中广泛存在，构成了重大的环境风险。为了解决这些限制，我们开发了一种主客体相互作用驱动的三明治状纳米复合膜，具有交替的多孔层和纤维层，用于快速去除利尿剂。hpβ - cd复合膜（hpβ - cd CM）在酸碱条件下均表现出稳定的吸附性能。在60 s内，hpβ - cd CM对氢氯噻嗪的去除率达到70%，其吸附速率常数比GAC和单组分β-环糊精聚合物高2-3倍。膜对HCTZ的最大吸附量为300 mg/g，对苯并氟甲肼和吲达帕胺的最大吸附量为200 mg/g。凭借其出色的吸附性能、成本效益和易于再生，HPβCD CM代表了高级水处理应用的一个有前途的解决方案。
