Dyes, pigments and metals are extensively used in food, paper, carpet, rubber, plastics, cosmetics, and textile industries, in order to color and finish products. As a result, they generate a considerable amount of coloured wastewater rich in organic, inorganic, and mineral substances which are continuously polluting the water bodies and affecting human and aquatic life. Besides these industries, urban and agricultural activities also generate effluents high in biochemical oxygen demand (BOD) and chemical oxygen demand (COD). In recent years, considerable research work has been done in this area and is underway to eliminate heavy metals particularly mercury (Hg), chromium (Cr), lead (Pb), selenium and cadmium (Cd) and synthetic dyes from polluted waters which have high toxicity and carcinogenicity.Currently a number of methods are in operation to decontaminate the polluted waters. Among several purification technologies, use of nanoparticles/composites have gained much attention as efficient purification technology due to its many advantages such as simple synthesis, special chemical and physical properties, unique photocatalytic activity and beneficial antimicrobial properties and high efficiency. The book Environmental Nanotechnology for Water Purification comprehensively covers and provides new insights on all nanoparticles, composites and advanced methods employed in water purification.

This book is organized into 12 important chapters that focus on the progress made by metal-based drugs as anticancer, antibacterial, antiviral, anti-inflammatory, and anti-neurodegenerative agents, as well as highlights the application areas of newly discovered metallodrugs. It can prove beneficial for researchers, investigators and scientists whose work involves inorganic and coordination chemistry, medical science, pharmacy, biotechnology and biomedical engineering.

This groundbreaking book covers the recent advances in sustainable technologies and developments, and describes how green chemistry and engineering practices are being applied and integrated in various industrial sectors. Over the past decade, the population explosion, rise in global warming, depletion of fossil fuel resources and environmental pollution have been the major driving force for promoting and implementing the principles of green chemistry and sustainable engineering in all sectors ranging from chemical to environmental sciences. It plays a growing role in the chemical processing industries. Green chemistry and engineering are relatively new areas focused on minimizing generations of pollution by utilizing alternative feedstocks, developing, selecting, and using less environmentally harmful solvents, finding new synthesis pathways, improving selectivity in reactions, generating less waste, avoiding the use of highly toxic compounds, and much more. In an effort to advance the discussion of green chemistry and engineering, this book contains 19 chapters describing greener approaches to the design and development of processes and products. The contributors describe the production of third generation biofuels, sustainable and economic production of hydrogen by water splitting using solar energy, efficient energy harvesting, mechanisms involved in the conversion of biomass, green nanocomposites, bio-based polymers, ionic liquids as green solvents, sustainable nitrogen fixation, bioremediation, and much more. The book aims at motivating chemists and engineers, as well as postgraduate and PhD students and postdocs to pay attention to an acute need for the implementation of green chemistry principles in the field of chemical engineering, biomedical engineering, agriculture, environmental engineering, chemical processing and material sciences. Audience The book offers an excellent resource for professors, postgraduate students, research scholars, and engineers working in the field of chemical engineering, environmental science, green chemistry, antimicrobial coatings, and material sciences.

This comprehensive book deals with the use of novel materials such as plantΓÇôderived agents and advanced nanocomposites for the removal of heavy metals, nitrates, and synthetic dyes. Water is an essential component for living organisms on planet earth and its pollution is one of the critical global environmental issues today. The influx of significant quantities of organic and inorganic waste, sediments, surfactants, synthetic dyes, sewage, and heavy metals into all types of water bodies has been increasing substantially over the past century due to rapid industrialization, population growth, agricultural activities, and other geological and environmental changes. These pollutants are very dangerous and are posing serious threat to us all. Advanced Materials for Wastewater Treatment brings together innovative methodologies and research strategies to remove toxic effluents from wastewaters. With contributions from leading scientists from all around the world, the book provides a comprehensive coverage of the current literature, upΓÇôtoΓÇôdate overviews of all aspects of toxic chemical remediation including the role of nanomaterials. Together they showcase in a very lucid manner an array of technologies that complement the traditional as well as advanced treatment practices of textile effluents. In particular, the book provides: UpΓÇôtoΓÇôdate overviews of all aspects of toxic chemical remediation The role of plants and abundantly available agroΓÇôwastes in the remediation of wastewater The removal of nitrates from wastewater using nanocomposites AudienceAdvanced Materials for Wastewater Treatment will be equally valuable to academicians, industry scientists and students involved with water treatment from a materials science, chemical engineering and nanotechnology perspective.
