Increased use of dyes compromises the visual quality of water sources and enhances the biochemical and chemical oxygen demand that promote toxicity, mutagenicity, and carcinogenicity of the environments. This book presents a broad-spectrum content of the functionalized materials and well-established methods, and a commercial perspective of various investigations conducted so far on dye degradation as an environmental cleaning application. It confines the emerging areas of advanced materials and efficient methods for the environmental remediation field as accommodating concepts. Describes fundamental as well as advancements in the field related to dye degradation and dye removal Discusses growth in the strategies to mitigate dye-related environmental issues through photocatalysis, electrocatalysis, and nanotechnology Covers photocatalysis micellar catalysis, electrocatalysis ion exchange materials, and nanomaterials Deals with various the synthetic approaches and future perspectives for development of the advanced materials Focuses on pertinent green and sustainability aspects related to the environment. This book is aimed at researchers and graduate students in environmental science, nanoscience, dyes, and chemistry.
