Excerpt from Application of Dyestuffs: To d104iles, Paper, Leather, and Other Materials The present volume has been the result of a comprehensive and more extended development of the author's earlier book entitled "Laboratory Manual of Dyeing and d104ile Chemistry." The latter was designed principally as a text-book for students, and necessarily omitted a great deal of matter of more general and practical interest. The present book, while still retaining many of the text-book features in order to adapt it to the needs of the student, has been greatly broadened in its scope so as to appeal to the interest of all those concerned in the application of dyestuffs. Dyestuffs are most largely used in the textile industries, and naturally this field has received the greatest attention at the hands of the author, but there has also been included a discussion of the use of dyes in other lines of industry; though the limitations of space, as well as the necessity of maintaining a proper balance in the subjects considered, has precluded more than a brief survey of these interesting fields. The method of presentation, as well as the subject matter herein contained, have been the outcome of a number of years of teaching on the part of the author, supplemented by a larger number of years of active professional practice in this field of applied chemistry. Care has been taken to avoid a too purely scientific generalization, else the volume would lose much of its value for purposes of instruction and information. The subject treated is a technical one, and an endeavor has been made to present it in a technical manner; that is to say, definite facts have been presented in a definite form. To this end an experimental outline has been distributed through the different chapters, both to act as a laboratory guide for the teacher and student and also to furnish concrete examples to the general reader. The author has endeavored as far as his limitations permit to incorporate in this book the latest knowledge of the subject. In the case of dyestuffs, this has been rather difficult at the present time, owing to the tremendous impetus the manufacture of dyestuffs has received in both America and England during the last few years, together with the shutting off from the world of the long-used and well-known German dyes.

In the last 10 years organic dyes, traditionally used for coloring textiles and other materials, have become increasingly important in the hi-tech industries of electronics and optoelectronics. They can be used in optical data storage, new solar cells and biomedical sensors.Functional Dyes discusses the synthesis of these new, high-value dyes and pigments as well as their applications and performance. The chapters are arranged so that the reader logically advances from the fundamental concepts to more practical aspects of the technology in which they are used.In providing the reader with current information on functional dye chemistry, as well as important developments within the field, Functional Dyes is a valuable information source for dye and material chemists, researchers and graduates, who want a summary of the key advances in the field over the last 10 years and an authoritative view on future developments.* Provides a broad introduction to the science technology of the functional dye application* Reviews recent advances on synthesis and characteristics of the functional dyes and their applications* Is a valuable information source for dye and material chemists and researchers

Contributions by scientists working in international laboratories provide the novice researcher with synthetic data and high-technology applications of leuco dyes. Covering leuco dye classes that exhibit reasonable stability, the book discusses photochromic materials that have wide-ranging applications in memory technology, leuco dyes for color photography, and a special class of dyes formulated by reduction instead of the oxidation process.

The Chemistry of Heterocyclic Compounds, since its inception, has been recognized as a cornerstone of heterocyclic chemistry. Each volume attempts to discuss all aspects – properties, synthesis, reactions, physiological and industrial significance – of a specific ring system. To keep the series up-to-date, supplementary volumes covering the recent literature on each individual ring system have been published. Many ring systems (such as pyridines and oxazoles) are treated in distinct books, each consisting of separate volumes or parts dealing with different individual topics. With all authors are recognized authorities, the Chemistry of Heterocyclic Chemistry is considered worldwide as the indispensable resource for organic, bioorganic, and medicinal chemists.

The use of synthetic chemical dyes in various industrial processes, including paper and pulp manufacturing, plastics, dyeing of cloth, leather treatment and printing, has increased considerably over the last few years, resulting in the release of dye-containing industrial effluents into the soil and aquatic ecosystems. The textile industry generates high-polluting wastewaters and their treatment is a very serious problem due to high total dissolved solids (TDS), presence of toxic heavy metals, and the non-biodegradable nature of the dyestuffs in the effluent. The chapters in this book provide an overview of the problem and its solution from different angles. These problems and solutions are presented in a genuinely holistic way by world-renowned researchers. Discussed are various promising techniques to remove dyes, including the use of nanotechnology, ultrasound, microwave, catalysts, biosorption, enzymatic treatments, advanced oxidation processes, etc., all of which are "green." Green Chemistry for Dyes Removal from Wastewater comprehensively discusses: Different types of dyes, their working and methodologies and various physical, chemical and biological treatment methods employed Application of advanced oxidation processes (AOPs) in dye removal whereby highly reactive hydroxyl radicals are generated chemically, photochemically and/or by radiolytic/ sonolytic means. The potential of ultrasound as an AOP is discussed as well. Nanotechnology in the treatment of dye removal types of adsorbents for removal of toxic pollutants from aquatic systems Photocatalytic oxidation process for dye degradation under both UV and visible light, application of solar light and solar photoreactor in dye degradation
