Decontamination of Heavy Metals

"From crystallization to membrane filtration, this book covers a wide range of subjects relating to heavy metals in the environment. The author explores the treatment, removal, recovery, disposal, management, and modeling of heavy metals. The text coversheavy adsorption processes including metal biosorption, ion exchange, and electrolysis processes for heavy metal decontamination. It also gives an overview of radioactive metals and their transportation in natural systems; presents various mathematical models for metal removal and recovery as well as transportation; and discusses a series of emerging technologies for metal treatment and management"--

This book covers fundamental theories of metal removal, including calculation of metal ion uptake in environmental systems. Professionals and students working in environmental engineering may find this book a very useful reference. ... This book is organized with a deliberately logical flow, defining concepts at the beginning, and gradually building up theories and applications. Dr. Gang Chen, Florida State University, USA

Résumé

Heavy metals, such as lead, chromium, cadmium, zinc, copper, and nickel, are important constituents of most living organisms, as well as many nonliving substances. Some heavy metals are essential for growth of biological and microbiological lives, yet their presence in excessive quantities is harmful to humans and interferes with many environmental processes. Heavy metals are also nonbiodegradable, making them more difficult to remediate. Decontamination of Heavy Metals: Processes, Mechanisms, and Applications tackles the subject of heavy metals in the environment, with special emphasis on their treatment, removal, recovery, disposal, management, and modeling.

Concepts, Cutting-Edge Technologies, and Applications

The book provides in-depth coverage of the major hazardous heavy metals that are found in water, land, and facilities and that have significant effects on public health and the environment. After an overview of heavy metal contamination, the text reviews the concepts and technologies of pollution prevention. It then examines technologies for metal decontamination, ranging from precipitationwhich is the most commonly usedto cutting-edge technologies such as precipitation-crystallization, ion exchange, membrane filtration, and electrolysis. Mathematical models for metal removal and recovery are also included.

Develop a Feasible Total Heavy Metal Control Program

Complementing other books in the Advances in Industrial and Hazardous Wastes Treatment series, this volume presents important research related to the remediation of heavy metals. Extensive references are included for readers who want to trace, duplicate, or improve on a specific industrial hazardous waste treatment practice. A comprehensive handbook for environmental professionals, researchers, and students, it provides technical information to help readers develop a feasible total metal control program that can benefit both industry and local municipalities.
