Available in PDF, EPUB and Kindle. Book excerpt: Dimethyl Sulfide (CH3SCH3, DMS) is the most important natural sulfur compound emitted from the ocean and its oxidation in the atmosphere has been proposed to play an important role in climate modification because some products from DMS oxidation become non-volatile and could participate in particle formation and growth processes. Although it has been demonstrated that aqueous phase reactions are potentially important for understanding DMS oxidation, the kinetics database for aqueous phase transformations is rather limited. In this work, a laser flash photolysis (LFP)? long path UV-visible absorption (LPA) technique was employed to investigate the kinetics of the aqueous phase reactions of four organic sulfur compounds produced from DMS oxidation, i.e., dimethylsulfoxide (DMSO), dimethyl-sulfone (DMSO2), methanesulfinate (MSI) and methanesulfonate (MS), with four important aqueous phase radicals, OH, SO4 & −, Cl and Cl2 & −. The temperature-dependent kinetics of the OH and SO4 & − reactions with DMSO, DMSO2 and MS were studied for the first time. OH is found to be the most reactive, while Cl2 & − is the least reactive toward all the sulfur species studied. The less oxidized DMSO and MSI are found to be more reactive than the more oxidized DMSO2 and MS for each radical. The kinetic data have been employed in a Trajectory Ensemble Model to simulate DMS oxidation in the marine atmosphere as a means of assessing the contribution of aqueous phase reactions to the growth of particulate matter. For the first time, oxidation of organic sulfur compounds by SO4 & −, Cl and Cl2 & − are included in the model to simulate DMS chemistry. Our simulations suggest that aqueous phase reactions contribute>97% of MS and %7E90% of NSS (Non-Seasalt Sulfate) production, and aqueous phase reactions of the organic sulfur compounds contribute 30% of total particle mass growth. When our kinetic data for the MS + OH reaction were used in the model, it was found that MS + OH could consume %7E20% of MS and produce %7E8% of NSS, within 3 days under typical marine atmospheric conditions.

Download or read book Sulfidic Sediments and Sedimentary Rocks written by David Rickard and published by Newnes. This book was released on 2012-12-31 with total page 813 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with sedimentary sulfides which are the most abundant authigenic minerals in sediments. Special emphasis is given to the biogeochemistry that plays such a central role in the formation of sedimentary sulfides. It will be of interest to scientists in a number of disciplines, including geology, microbiology, chemistry and environmental science. The sulfur system is important to environmental scientists considering the present and future effects of pollution and anoxia. The development of the sulfur system – particularly the characteristics of ocean anoxia over the last 200 Ma – is useful in predicting the future fate of the Earth surface system as well as in understanding the past. The biochemistry and microbiology of the sulfur system are key to understanding microbial ecology and the evolution of life. First monograph on sedimentary sulfides, covering the ancient and modern sedimentary sulfide systems Comprehensive, integrating chemistry, microbiology, geology and environmental science All key references are included and discussed

Available in PDF, EPUB and Kindle. Book excerpt: Explains the fundamental theory and mathematics of water and wastewater treatment processes By carefully explaining both the underlying theory and the underlying mathematics, this text enables readers to fully grasp the fundamentals of physical and chemical treatment processes for water and wastewater. Throughout the book, the authors use detailed examples to illustrate real-world challenges and their solutions, including step-by-step mathematical calculations. Each chapter ends with a set of problems that enable readers to put their knowledge into practice by developing and analyzing complex processes for the removal of soluble and particulate materials in order to ensure the safety of our water supplies. Designed to give readers a deep understanding of how water treatment processes actually work, Water Quality Engineering explores: Application of mass balances in continuous flow systems, enabling readers to understand and predict changes in water quality Processes for removing soluble contaminants from water, including treatment of municipal and industrial wastes Processes for removing particulate materials from water Membrane processes to remove both soluble and particulate materials Following the discussion of mass balances in continuous flow systems in the first part of the book, the authors explain and analyze water treatment processes in subsequent chapters by setting forth the relevant mass balance for the process, reactor geometry, and flow pattern under consideration. With its many examples and problem sets, Water Quality Engineering is recommended as a textbook for graduate courses in physical and chemical treatment processes for water and wastewater. By drawing together the most recent research findings and industry practices, this text is also recommended for professional environmental engineers in search of a contemporary perspective on water and wastewater treatment processes.

Available in PDF, EPUB and Kindle. Book excerpt: This second edition demonstrates how chemistry influences the design of water treatment plants and how it should influence the design. Historically, water treatment plants have been designed from hydraulic considerations with little regard to chemical aspects. The many chemical reactions used for removal of pollutants from water simply cannot be forced to occur within current designs. This book re-examines this traditional approach in light of today's water quality and treatment. Will current water treatment processes be sufficient to meet future demands or will new processes have to be devised? Chemistry of Water Treatment assesses the chemical and physical efficacies of current processes to meet the demands of the Safe Drinking water Act, providing expert information to persons responsible for the production of potable water into the next century.
