Foreword

Synthetic dyes are a major part of dyes utilized by the textile industry. Organic dyes are the new chemicals that are extensively used in the textile industry nowadays. Most of these dyes are toxic and potentially carcinogenic in nature and pose major threats and create environmental problems. While dyeing, not all the dyes are adsorbed by the fabric materials and a considerable part is left as textile effluent. This effluent will mix with water bodies and create environmental hazards. Therefore, the treatment of textile effluents, especially dye removal, is an imperative step for environmental remediation. The removed dye is also a secondary pollutant to the environment. Therefore, the conversion of dye molecules to benign molecules is the ultimate step for environmental remediation. The conversion of carcinogenic dye molecules to an environmentally benign molecule is called dye degradation. From the industrial perspective, the process of conversion should be not only efficient but also cost-effective.

The editors have chosen the interesting aspects of dye degradation. The book “Advances in Dye Degradation” highlights the recent advantages of dye degradation pathways. However, without a basic understanding, the advanced perspective will have no meaning. Hence, Volume I of this book series deals with the fundamental aspects. In this work, the authors have discussed the nature of dye molecules, adverse effects, environmental problems caused by the dye molecules and their remediation process. The toxicity of the dyes is discussed in detail, and the application of nanotechnology, electrochemical and biological processes is also discussed. Since the advanced oxidation process is one of the important methods of the dye degradation process, the basic mechanism of photocatalytic dye degradation is also discussed in detail. This book deals with the basics of most of the relevant topics in the field of dye degradation, and it will certainly be useful for students as well as researchers.
