Green Chemistry for Dyes Removal from Waste Water

The use of synthetic chemical dyes in various industrialprocesses, including paper and pulp manufacturing, plastics, dyeingof cloth, leather treatment and printing, has increasedconsiderably over the last few years, resulting in the release ofdye-containing industrial effluents into the soil and aquaticecosystems. The textile industry generates high-pollutingwastewaters and their treatment is a very serious problem due tohigh total dissolved solids (TDS), presence of toxic heavy metals,and the non-biodegradable nature of the dyestuffs in theeffluent.The chapters in this book provide an overview of the problem andits solution from different angles. These problems and solutionsare presented in a genuinely holistic way by world-renownedresearchers. Discussed are various promising techniques to removedyes, including the use of nanotechnology, ultrasound, microwave,catalysts, biosorption, enzymatic treatments, advanced oxidationprocesses, etc., all of which are green.Green Chemistry for Dyes Removal from Wastewatercomprehensively discusses:* Different types of dyes, their working and methodologies andvarious physical, chemical and biological treatment methodsemployed* Application of advanced oxidation processes (AOPs) in dyeremoval whereby highly reactive hydroxyl radicals are generatedchemically, 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 ofadsorbents for removal of toxic pollutants from aquaticsystems* Photocatalytic oxidation process for dye degradation under bothUV and visible light, application of solar light and solarphotoreactor in dye degradation
