This book explores the potential of advanced microwave techniques, specifically microwave-assisted pyrolysis, for the production, adsorption, and regeneration of activated carbon (AC) as a promising solution to address wastewater pollution caused by dyes. The author begins with a chapter devoted to the environmental implications of water pollution and emphasizes the characteristics of dyes and various treatment techniques for their removal. The advantages and disadvantages of commercially available activated carbon are also discussed, along with the determinants for effective adsorption using high-quality activated carbon. Additionally, the chapter delves into the different types of adsorbents, including agricultural and industrial waste, as well as bioadsorbents such as microorganisms. In Chapter 2, readers will find the latest trends in using microwave techniques for the activation process. In this chapter, the author elucidates the characteristics and mechanism of microwave heating and compares it with conventional heating methods. The advantages of microwave techniques, such as improved activation procedures and the influence of different factors, are explored. Various modeling and optimization approaches for adsorption and different techniques for analyzing the surface chemistry of activated carbons are also discussed. Furthermore, the chapter showcases the applications of microwave-assisted activated carbon for dye removal. The book closes with a chapter devoted to the recycling and regeneration of spent activated carbon (SAC) using microwave techniques. In this chapter, the author examines the procedures for SAC regeneration through microwave-assisted pyrolysis and highlights the advantages over conventional heating methods. The applications of microwave-assisted activated carbon regeneration and other miscellaneous technologies utilizing microwave heating for AC production and SAC regeneration are also explored. Given its breadth, this book is a valuable resource for researchers, professionals, and policymakers in the field of environmental science and engineering.

Also, the properties of different carbon nanomaterials for adsorption applications are covered. The third chapter presents the kinetic and equilibrium models of adsorption, processing of experimental data and adsorption process peculiarities. Environmental and biological applications of carbon nanomaterials are listed in the last chapter. This book is written from an application-oriented perspective and is useful for all those interested in nanoadsorbents.

This timely and important book aims to help achieve a more sustainable textile industry; researchers from both textile and environmental domains will benefit from reading it. Since it is imperative to rehabilitate our damaged environmental ecosystems, there is a pressing demand for more sustainable green processes in the textile and clothing industry. As a consequence, greater emphasis needs to be placed on research into eco-friendly processes particularly suited for this industry. With this goal in mind, all environmental aspects relating to the textile and clothing industry are discussed in this book in four broad areas: Highlights the negative impact on the environment by textile industries; Discusses textiles finishing by natural or eco-friendly means; Promotes natural dyes as environment-friendly alternatives to synthetics; Reviews textile effluents remediation via chemical, physical and bioremediation. Included in the 11 informative chapters are topics covering the correlation between the environment and the processing and utilization of textiles and clothing. The book opens with a discussion on the direct impact that the textile industry has on the environment. The hazardous environmental consequences that synthetic dyes used to color textiles have on the environment are highlighted in the next chapter. Greener alternatives to dyeing are discussed in detail in the next chapters followed by a discussion of eco-friendly ways of finishing textiles. The book concludes with a section of chapters providing solutions to address the environmental hazards associated with the textile industry.

It is particularly appropriate that a volume concerned with dye chemistry should be included in the series Topics in Applied Chemistry. The development of the dye industry has been inexorably linked not only with the development of the chemical industry but also with organic chemistry itself since the middle of the last century. The position of dye chemistry at the forefront of chemical 1945 and more markedly so during the last advance has declined somewhat since 15 years, with pharmaceutical and medicinal chemistry assuming an increasingly prominent position. Nevertheless, dye production still accounts for a significant portion of the business of most major chemical companies. The field of dye chemistry has stimulated the publication of many books over the years but surprisingly few have concentrated on or even included the practical aspects of dye synthesis and application. Thus, the present volume is designed to fulfill that need and provide the reader with an account of advances in dye chemistry, concentrating on more recent work and giving, in a single volume, synthetic detail and methods of application of the most important classes, information which will be invaluable to both student and research chemist alike.
