Abstract

Water is a vital component of our existence. Many human activities, such as improper waste disposal from households, industries, hospitals, and synthetic processes, are major contributors to the contamination of water streams. It is the responsibility of every individual to safeguard water resources and reduce pollution. Among the various available wastewater treatment (WWT) methods, smart nanomaterials stand out for their effectiveness in pollutant removal through absorption and adsorption. This paper examines the application of valuable smart nanomaterials in treating wastewater. Various nanomaterials, including cellulose nanocrystals (CNC), cellulose nanofibrils (CNF), nanoadsorbents, nanometals, nanofilters, nanocatalysts, carbon nanotubes (CNTs), nanosilver, nanotitanium dioxide, magnetic nanoparticles, nanozero-valent metallic nanoparticles, nanocomposites, nanofibers, and quantum dots, are identified as promising candidates for WWT. These smart nanomaterials efficiently eliminate toxic substances, microplastics, nanoplastics, and polythene particulates from wastewater. Additionally, the paper discusses comparative studies on the purification efficiency of nanoscience technology versus conventional methods.

利用智能纳米材料处理废水的尖端技术：近期趋势和未来进展

水是我们生存的重要组成部分。许多人类活动，如家庭、工业、医院和合成过程中的不当废物处理，都是造成水流污染的主要原因。保护水资源和减少污染是每个人的责任。在现有的各种废水处理（WWT）方法中，智能纳米材料因其通过吸收和吸附去除污染物的功效而脱颖而出。本文探讨了有价值的智能纳米材料在废水处理中的应用。各种纳米材料，包括纤维素纳米晶体 (CNC)、纤维素纳米纤维 (CNF)、纳米吸附剂、纳米金属、纳米过滤器、纳米催化剂、纳米碳管 (CNT)、纳米银、纳米二氧化钛、磁性纳米颗粒、纳米零价金属纳米颗粒、纳米复合材料、纳米纤维和量子点，都被认为是有希望用于 WWT 的候选材料。这些智能纳米材料可有效消除废水中的有毒物质、微塑料、纳米塑料和聚乙烯微粒。此外，本文还讨论了纳米科学技术与传统方法在净化效率方面的比较研究。
