Removal of toxic elements from wastewater effluent has got a lot of attention because of their severe negative effects on human and environmental health. In the past few years, rapid urbanization and industrial activities in developing countries have exacerbated the destruction of the environment. Most of the wastewater effluents are discharged untreated or inadequately treated, which has become a major concern due to its impact on sustainability and the environment. This is imperative to implement, innovative and resourceful wastewater treatment technologies requiring low investment. Among the various treatment technologies, cutting-edge processes in nano-material sciences have recently piqued the interest of scientists. Nanohybrid absorbents have the potential in improving wastewater treatment and increase water supply by utilizing unconventional water resources. Carbon nanotubes, titanium oxide, manganese oxide, activated carbon (AC), magnesium oxide, graphene, ferric oxides, and zinc oxide are examples of nano-adsorbents that are used to eliminate pollutants. This also demonstrated the effective removal of contaminants along with the harmful effects of chemicals, colorants, and metals found in wastewater. The present manuscript examines potential advances in nanotechnology in wastewater treatment for the prevention of water and soil pollution. This systematic review aims to highlight the importance of nanohybrid absorbents treatment technology for wastewater treatment and to explain how nanohybrid absorbents have the potential to revolutionize industrial pollution. There are also other published review articles on this topic but the present review covers an in-depth information on nano-adsorbents and their targeted contaminants.
由于有毒元素对人类和环境健康的严重负面影响，从废水废水中去除有毒元素已引起了广泛关注。在过去的几年中，发展中国家的快速城市化和工业活动加剧了环境破坏。大多数废水未经处理或处理不当就被排放，这由于其对可持续性和环境的影响而成为主要关注点。因此，必须采用创新且资源节约型的低投资废水处理技术。在各种处理技术中，纳米材料科学中的前沿工艺最近引起了科学家的兴趣。纳米杂化吸收剂具有通过利用非常规水资源来改善废水处理和增加供水的潜力。碳纳米管、氧化钛、氧化锰、活性炭 (AC)、氧化镁、石墨烯、氧化铁和氧化锌是用于去除污染物的纳米吸附剂的示例。这也证明了可以有效去除废水中的污染物以及化学物质、染料和金属的有害影响。本文研究了纳米技术在废水处理中的潜在进展，以防止水和土壤污染。本系统评价旨在强调纳米杂化吸收剂处理技术在废水处理中的重要性，并解释纳米杂化吸收剂如何具有彻底改变工业污染的潜力。关于这个主题也有其他已发表的评论文章，但本评论涵盖了有关纳米吸附剂及其目标污染物的更深入信息。
