Chelating Agents for Land Decontamination Technologies examines the application of chelating agents for the treatment of soil contaminated with metals. Contaminated land remediation is a widespread and costly problem, and the traditional excavation-and-disposal treatment method is not a sustainable solution. Chelating agents (organic compounds that can bind metal ions) are an attractive new technology for land decontamination, because chelating agents enhance metal extraction from contaminated soil or sediment and facilitate metal mobility in subsurface soils. Chapters in this book cover the process fundamentals as well as engineering applications and recent advances for the use of chelating agents in soil washing, soil flushing, phytoremediation, and electrokinetic remediation. They address the application of chelating agents for both ex situ and in situ soil remediation technologies. The extensive use of illustrations and summary tables is combined with up-to-date references. This compilation of engineering applications and research findings for different chelating agent enhanced remediation technologies will be useful to environmental engineers, scientists, and decision makers regarding contaminated land remediation.
Nanotechnologies, 'the engine of the next Industrial Revolution', represent the new wave of research for chemical and industrial innovation. However, with any new technology or compound, comes the threat of harm to humans and natural ecosystems. Research into the environmental effects, as well as the ethical, legal, and social implications of nanotechnologies and nanoproducts has never been more important. ""Nanotechnologies for Water Environment Applications"" provides the current status of synthesis and characterization of nanomaterials, as well as the environmental effects of nanotechnology. This publication specifically targets the major applications of nanotechnologies in various water environments; issues related to the fate and transport of nanomaterials in aquatic environments; engineered nanomaterials as emerging contaminants in water; the environmental risks, and related management, of nanomaterials. Extensive up-to-date references are provided. This book will be useful to undergraduate and graduate students of engineering, educators, scientists, engineers, government officers, decision makers, process managers, and practicing professionals.
New chemical compounds are constantly being created to meet specific industrial applications and for human uses. Release of these compounds into the environment is inevitable and their contamination of natural resources, as well as their effect on human health, remain an important global ecological concern. Many compounds degrade in the presence of various natural processes, so there is a need to understand whether new compounds will persist in the environment or will eventually break down innocuously. ""Natural Processes and Systems for Hazardous Waste Treatment"" discusses the various natural processes for the attenuation and degradation of hazardous compounds and these processes' application in inexpensive natural systems. Major attenuation processes that are covered include: sorption and sequestration, biodegradation and assimilation processes, photo-processes, phyto-processes, oxidation-reduction, and physical processes. Extensive up-to-date references are presented, as are numerous illustrations, tables, and case studies. This book will serve as a reference for undergraduate or graduate students, as well as for practicing professionals.
This work provides a tool for engineers or decision-makers to evaluate the applicability of Zero-valent iron (Fe0) and give them the technical solutions about the engineering application of Fe0 to contaminated sites. Written from both theoretical and practical viewpoints, this book covers the comprehensive principles, latest research findings, and innovative development of Fe0 in hazardous waste and inorganics removal. Moreover, the approaches of design, installation and performance evaluation of Fe0-based PRBs are also covered.
