Any mention of the "greenhouse effect" tends to ignite controversy. While the rising atmospheric concentrations of greenhouse gases-especially carbon dioxide- are certainly among the most pressing issues today, theoretical and perceived consequences have been subject to conjecture and misinformation.That raging debate has obscured an important fact: scientists and engineers are hard at work on methods to reduce CO2 emissions, and devise practical methods for their remediation.Greenhouse Gas Carbon Dioxide Mitigation: Science and Technologysheds light on the most recent advancements, documented by two of the world's leading researchers on CO2.Aware of the complexity and still-unknown factors behind climatic change, the authors consider the need to make CO2 mitigation viable for both environmental and economic gain. To that end, Professor Halmann offers new insights into interesting chemical pathways for the conversion of CO2 to useful products. Steinberg adds real-life engineering solutions, applicable to heavy CO2-producing industrial processes, and improving efficiency of energy conversion.Exciting theories and pilot projects are also testing the potential for CO2 utilization, conversion, reduction, and disposal. Greenhouse Gas Carbon Dioxide Mitigation: Science and Technology reports on the use of biomass, such as ocean fertilization and "energy farms," to put CO2 to practical and safe use.Professional and academic readers involved with CO2 research will find Greenhouse Gas Carbon Dioxide Mitigation: Science and Technology an invaluable roadmap for information and inspiration-a way to move beyond argument, and into action.

Photodegradation of Water Pollutants, the only complete survey available of current photocatalytic methods for treating water pollutants, covers all aspects of light-stimulated detoxification. Ideal for researchers and students, this new book explains methods for pollution treatment that have proven more effective than conventional biodegradation.Photodegradation of Water Pollutants examines advanced oxidation processes that have been successful in treating the chemical substances produced by industrial effluents and intensive agriculture. These oxidation processes include irradiation with ultraviolet or visible light, the use of homogenous sensitizers, such as dyes, and the use of heterogeneous photocatalysts, such as dispersed semiconductors.In addition, Photodegradation of Water Pollutants addresses the naturally occurring self-cleaning of some pollutants in sunlit surface waters, as well as several alternative non-photochemical approaches to water treatment. Available treatment options are discussed for the main groups of water pollutants, including toxic inorganic ions (cyanides, heavy metals), hydrocarbon derivatives (oil spills, surfactants, pulp and paper wastes), halocarbons, organo-N, organo-P, and organo-S compounds. The text also contains a unique section on the economics of advanced oxidation pollution treatments.

Chemical Fixation of Carbon Dioxide presents new concepts and results from research into the problems caused by increasing levels of carbon dioxide. The book discusses the limitations of natural plant photosynthesis as a sink for carbon dioxide and emphasizes chemical fixation as an important alternative. A number of significant topics are covered, including new coupling reactions for producing compounds such as carbamates, urethanes, and heterocyclic structures; new catalyst systems, particularly for methanation and methanol synthesis; the use of homogeneous solution photosensitizers and heterogeneous semiconductor photocatalysts to photoreduce carbon dioxide with visible light and sunlight; and electrochemical reduction.This book will be a useful reference for organic chemists working on environmental problems, chemical engineers, environmental chemists, professionals at research facilities, and students.
