Liquid Chromatography of Natural Pigments and Synthetic Dyes by Tibor Cserháti Pdf

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

Microbial Degradation of Synthetic Dyes in Wastewaters by Shree Nath Singh Pdf

Today synthetic dyes are used extensively in the textile dyeing, paper printing, color photography, pharmaceuticals, food and drink, cosmetic and leather industries. As of now, over 100,000 different dyes are available, with an annual production of over 700,000 metric tons. These industries discharge an enormous amount of colored effluents into natural water bodies, with or without treatment. The textile industry alone discharges 280,000 tons of dyes every year, making it the largest contributor to colored effluent discharge. Although a variety of treatment technologies are available, including adsorption, chemical oxidation, precipitation, coagulation, filtration electrolysis and photodegradation, biological and microbiological methods employing activated sludge, pure cultures, microbial consortia and degradative enzymes are economically viable, effective and environmentally responsible options. As such, this book gathers review articles from international experts working on the microbial degradation of synthetic dyes, offering readers the latest information on the subject. It is intended as a quick reference guide for academics, scientists and industrialists around the world.

Synthetic Dyes in Biology, Medicine And Chemistry by Edward Gurr Pdf

Synthetic Dyes in Biology, Medicine and Chemistry is a guide in selecting dyes for special purposes in biology, medicine, chemistry, and other related fields. It aims to help professionals including histologists, cytologists, and other biology and medicine experts, such as chemists and general scientists. The dyes discussed in this book are categorized in 17 different classes according to the nature of their salt-forming sidechains, the colligators. This book also presents the uses of each dye. The spectral curve, which is the ionic and/or molecular weight of each dye, is also covered in this book. Likewise, this text provides the structural and empirical formulae of the spectral curve. Part I tackles various groups of dyes. These groups are the non-ionic, anionic, and cationic dyes. The anionic dyes are further grouped as wholly acid, weakly amphoteric, and moderately or strongly amphoteric. The subsequent part deals with the examples of dyes that do not fit the categories mentioned in Part I. These miscellaneous dyes are vat, reactive, disperse, and ingrain dyes. Part III presents the dyes in different tables according to wavelength of maximum absorption and ionic or molecular weight. This book also covers the stabilized diazonium salts and substituted napthols.

Hazardous Materials and Wastewater by Allison A. Lewinsky Pdf

Hazardous waste is a waste with properties that make it dangerous or potentially harmful to human health or the environment. Hazardous waste generally exhibits one or more of these characteristics: ignitability, corrosivity, reactivity or toxicity. The universe of hazardous wastes is large and diverse. Hazardous wastes can be liquids, solids, contained gases, or sludges. They can be the by-products of manufacturing processes or simply discarded commercial products, like cleaning fluids or pesticides. One major type is radioactive waste. This book brings together the latest research in this diverse field.
