Series: Advances in Industrial and Hazardous Wastes Treatment.

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 covers heavy 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.

Reviews

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.
