Book Description
More than one and a half decades have passed since the last book was published describing developments in the analytical chemistry of synthetic colorants. In the intervening period, the scope and technical capabilities of instrumentation for analysing dyes and pigments has significantly expanded. It is now possible to rapidly resolve a number of problems whose solutions were previously either unattainable or very difficult to achieve. For instance, the unambiguous assignment of all the signals in the proton NMR spectrum of a trisazo direct dye, and the confirmation of the molecular weight of involatile, and, in particular, sulphonated dyes, without derivatisation, are now routine analytical techniques in many laboratories today. In addition, it is now possible to record the NMR spectrum of a dye molecule on less than 1 mg of material, and we are no longer limited to solution spectra, since solid samples can now be routinely analysed in NMR experiments. Whilst not attempting to be all encompassing, this volume is intended to bridge the gap between what was covered in the earlier work edited by Professor Venkataraman and the developments which have since ensued in some key areas. It provides important updates in X-ray crystallography, proton NMR, IR spectroscopy and mass spectrometry, and additionally covers topics such as ESR, micro spectrophotometry and emission spectroscopy.

Book Description
In the last two decades the EPA and other national andinternational agencies have placed increasingly strict regulationson the manufacture and use of synthetic colorants. The pigment anddye industry has had to develop the technology necessary to analyzeand remediate pollutants in wastewater. Although these efforts haveproduced a considerable volume of information, until now, no singlebook has provided an organized, comprehensive treatment of theenvironmental chemistry of synthetic colorants. Environmental Chemistry of Dyes and Pigments is the firstcomprehensive reference to address the environmental problems posedby synthetic colorants, and to provide a forum for the solutionsproposed by industry, government, and academia. Focusing ondevelopments in the field over the past two decades, it deals withall aspects of colored wastewater treatment, the disposal of dyes,analytical methods, toxicity, and regulatory questions. In its coverage of wastewater treatment, this book addresses boththe most commonly used methods and those specifically designed toaddress pollution problems at the source by analyzing for andremoving dyes and pollutants from wastewater effluent. Throughout,real-world data on a wide variety of dyes and dye intermediates isprovided, as well as cost-effective strategies for dealing withwastewater treatment. In addition, several chapters are devoted to the perspectives ofnational and international experts on regulations governing themanufacture, handling, use, and disposal of synthetic dyes andpigments. The impact these regulations have had on both U.S. andforeign industry is also discussed. A complete, comprehensive, and up-to-date guide to pollutionprevention in the dyestuff and textile industries Environmental Chemistry of Dyes and Pigments is the onlyself-contained volume that focuses on the environmental impact ofsynthetic dyes and pigments. Contributions by international expertsfrom industry, academia, and government make this an indispensablebook for anyone dealing with the environmental problems posed bysynthetic colorants. It covers the entire range of environmentalissues, from waste treatment and analysis to pollution preventionand government regulations. Covers the latest wastewater treatment methods Shows how to use recycling and reusing methods effectively, whilecutting production costs Describes state-of-the-art technology, including the PACT(r)system Explains analysis techniques, including spectrometry andionization Covers legislative issues and the regulatory status of variouscompounds in both the United States and abroad Examines the various pollution prevention programs instituted bygovernment and industry Bridging the gap between industrial interests and environmentalconcerns, Environmental Chemistry of Dyes and Pigments stands as aninvaluable resource for scientists, researchers, and engineers inthe textile and dyestuff industries, and in the environmentalsciences. It is also an extremely useful text for environmentalscience students.

Book Description
This latest volume in the series entitled Liquid Chromatography of Natural Pigments and Synthetic Dyes presents an overview of the latest developments in the field while critically evaluating this method of analysis and providing comparisons of the various liquid chromatographic separation techniques that are currently available. Natural pigments and synthetic dyes are extensively used in various fields of everyday life including food production, textile industry, paper production, agricultural practice and research and water science and technology. Besides their capacity for increasing the marketability of products, natural pigments have shown advantageous biological activity as antioxidants and anticancer agents. On the negative side, synthetic pigments have a significant impact on the environment and can cause adverse toxicological side effects. Both pigment classes exhibit considerable structural diversity. As the stability of the pigments against hydrolysis, oxidation and other environmental and technological conditions is markedly different, the exact determination of the pigment composition may help for the prediction of the shelf-life of products and the assessment of the influence of technological steps on the pigment fractions resulting in more consumer friend processing methods. Furthermore, the qualitative determination and identification of the pigments may contribute to the establishment of the provenance of the product. The unique separation capacity of liquid chromatographic (LC) techniques makes it a method of preference for the analysis of pigments in any complicated accompanying matrices.* an overview of the latest developments in the field* a critical evaluation of results from this form of analysis* a comparison of the various LC (liquid chromatographic) separation techniques* future trends in the LC analysis of pigments

Book Description
Metal- Free Synthetic Organic Dyes is a comprehensive guide to the synthetic, organic dyes that are classified by their chemical structure. As synthetic dyes are playing an increasingly important role in modern life, with applications in both industry and scientific research, this book provides insights on the many research attempts that have been made to explore new photosensitizers in the development of dye sensitized solar cells (DSCs). These novel photosensitizers have incorporated, within their structure, different organic groups, such as coumarins, cyanines, hemicyanines, indolines, triphenylamines, bis(dimethylfluorenyl) aminophenyls, phenothiazines, tetrahydroquinolines, carbazoles, polyenes, fluorenes, and many others. This comprehensive resource contains color figures and schemes for each dye discussed, and is an invaluable resource for organic, inorganic and analytical chemists working in academia and industry. - Features a discussion of the synthesis of the new, high-value synthetic dyes and pigments and their applications and performance - Includes coverage of new photosensitizers and their role in the development of dye sensitized solar cells (DSCs) - Covers synthesis of the functional dyes that are ideal for applications in the dye and pigment industry, textiles, color science, solar energy materials and solar cells, biomedical sensors, advanced materials, structure and synthesis of materials, and more

Book Description
This book provides an up-to-date insight into the chemistry behind the colour of the dyes and pigments that make our world so colourful. The impressive breadth of coverage starts with a dip into the history of colour science. Colour Chemistry then goes on to look at the structure and synthesis of the various dyes and pigments, along with their applications in the traditional areas of textiles, coatings and plastics, and also the ever-expanding range of "high-tech" applications. Also discussed are some of the environmental issues associated with the manufacture and use of colour. The broad and balanced coverage presented in this book makes it ideal for students and graduates. In addition, many specialists in industry or academia will also benefit from the overview of the subject that is provided.
