Abstract

Water disinfection processes such as sedimentation, filtration, and chemical or biological degradation are not fully capable of destroying emerging contaminants or certain types of bacteria. Nanotechnology can potentially be employed to address these challenges posed by various contaminants and microorganisms. This paper highlights the advanced nanomaterials and approaches for the removal of pollutants and contaminant from aqueous solutions, functionalized nanostructured materials and processes in water and wastewater treatment technologies, removal/recovery of heavy metals by amorphous metal oxide nanoparticles, nanoparticle-assisted nanofiltration, and development of innovative and natural-based nanosorbents for water treatment. In this review, recent nanotechnological advances and deployment of polymeric nanoadsorbents for the removal of toxic contaminants/pollutants from wastewater streams are discussed.

摘要

水消毒过程，如沉淀、过滤和化学或生物降解，不能完全消灭新出现的污染物或某些类型的细菌。纳米技术可以潜在地用于解决各种污染物和微生物带来的这些挑战。本文重点介绍了用于从水溶液中去除污染物和污染物的先进纳米材料和方法、水和废水处理技术中的功能化纳米结构材料和工艺、通过无定形金属氧化物纳米颗粒去除/回收重金属、纳米颗粒辅助纳米过滤和开发用于水处理的创新和天然纳米吸附剂。在这次审查中，
