Nanotechnology is an advanced technology holding promise for high-efficiency treatment of wastewater. The positive impacts of nanotechnology on the development of greener and cleaner technologies include substantial health and environmental advantages. The potential applications of nanotechnology in managing clean water resources and improving the working efficiency of conventional environmental remediation technologies are still being explored. This book aims to provide comprehensive information on the effective utilization of nanotechnology for environmental remediation, particularly water purification, covering nanoadsorbents, nanophotocatalysts, nanobiochar, nanocomposites, nanohydrogels, various metal-based binary and ternary nanocomposites, polymeric nanocomposites, and more, for effective degradation/removal of organic/inorganic pollutants from waste. The approaches to synthesizing these nanomaterials, their working mechanisms in wastewater treatment, and efficiency comparisons with related and conventional technologies are also presented. The detoxification of hazardous wastewater components due to nanomaterials is of utmost importance, and detection technologies for these toxins are also among the prime needs of the remediation scenario. Therefore some detection technologies based on nanosensors are reviewed, including their working mechanisms. Various mechanisms available for use in water remediation are covered as well.
