This book was released on 2013-03-09 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Environmental Chemistry of Dyes and Pigments written by Abraham Reife and published by John Wiley & Sons. This book was released on 1996-01-05 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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

Download or read book Application of Analytical Chemistry to Foods and Food Technology written by Daniele Naviglio and published by MDPI. This book was released on 2021-02-22 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: The application of analytical chemistry to the food sector allows the determination of the chemical composition of foods and the properties of their constituents, contributing to the definition of their nutritional and commodity value. Furthermore, it is possible to study the chemical modifications that food constituents undergo as a result of the treatments they undergo (food technology). Food analysis, therefore, allows us not only to determine the quality of a product or its nutritional value, but also to reveal adulterations and identify the presence of xenobiotic substances potentially harmful to human health. Furthermore, some foods, especially those of plant origin, contain numerous substances with beneficial effects on health. While these functional compounds can be obtained from a correct diet, they can also be extracted from food matrices for the formulation of nutraceutical products or added to foods by technological or biotechnological means for the production of functional foods. On the other hand, the enormous growth of the food industry over the last 50 years has broadened the field of application of analytical chemistry to encompass not only food but also food technology, which is fundamental for increasing the production of all types of food.
