Water contamination is a worldwide critical issue for the present society to avoid competition and maintain an environmentally friendly scenario. Removal of various pollutants including inorganic and organic compounds from water is a big challenge nowadays. Worldwide attention to promote polluted water and technologies related to its treatment has been adversely increased. The utilization of metal/metal oxide nanoparticles (NPs) for this purpose has gained much attention due to its exceptional properties imparted by reduced size and effective surface area. Moreover, metal/metal oxide NPs-based innovation for improved expulsion productivity is an ingenious area for research and development but the use of such NPs presents some serious risks. Herein, the advanced requisition of NPs for polluted water treatment is highlighted along with the difficulties related to them and their toxic impacts when used as water purifiers. Additionally, the plausible fate of metal/metal oxide NPs incorporated in the water for purification and salient future challenges are deliberated.
水污染是当前社会避免竞争和保持环境友好型的一个全球性关键问题。从水中去除各种污染物，包括无机和有机化合物，是当今面临的一个巨大挑战。全球都在关注促进污染水和与水污染处理相关的技术，这方面的关注度一直在增加。由于尺寸减小和有效表面积增大带来的特殊性质，金属/金属氧化物纳米颗粒（NPs）的利用为此目的引起了广泛关注。此外，基于金属/金属氧化物 NPs 的创新以提高去除效率是研究和开发的一个巧妙领域，但此类 NPs 的使用存在一些严重的风险。本文重点介绍了 NPs 用于处理受污染水的先进要求，以及它们作为水净化器使用时所带来的相关困难和毒性影响。此外，还讨论了为净化而纳入水中的金属/金属氧化物 NPs 的可能归宿以及突出的未来挑战。
