Advanced Nanomaterials for Removal of Emerging Organic Pollutants From Water

Abstract

Advanced carbon-based nanomaterials have generated significant attention as nanomaterials and composites for the adsorptive removal of several kinds of contaminants from water due to their physicochemical properties. According to the United Nations Sustainable Development Goals (SDG 6), providing clean water remains a significant challenge in developing nations and has been the focus of a lot of global research and development. The occurrence of emerging organic pollutants in the aquatic environment poses severe negative effects on environmental matrices and people. Pharmaceuticals, pesticides, polycyclic aromatic hydrocarbons, dyes, and industrial additives are examples of emerging pollutants that are often detected in water systems. Conventional wastewater treatment plants have been unable to effectively remove many of these trace pollutants. The classes of advanced sorbent materials described in this chapter include one- and two-dimensional carbon-based materials, such as graphene, carbon nanotubes, and their composites. Due to aspects like cost, effectiveness, simplicity of use, and reusability, the adsorption process is recognized as the most studied and used remediation technology. It is recommended that ecofriendly and sustainable methods be explored to mitigate the distressing consequences of rising organic chemical contaminants in water systems.
