Zero-Valent Iron Reactive Materials for Hazardous Waste and Inorganics Removal

Abstract

  • Sponsored by the Hazardous, Toxic, and Radioactive Waste Management Committee of the Environmental and Water Resources Institute of ASCE.

    This report provides up-to-date technical information and state-of-the-art research findings on the use of zero-valent iron reactive materials to remove contaminants frequently found in groundwater. Covering both the theoretical and the practical, this book covers the comprehensive principles, latest research findings, and innovative developments in hazardous waste and inorganics removal.

    To establish a basic understanding of the reactive materials, the scientific principles of chemical reduction reactions, reductive precipitation, and adsorption processes are explained. Then the book describes the design methodology for the full-scale application of zero-valent iron in contaminated sites, as well as approaches to performance evaluation of the reactive materials. The book includes case studies and covers the design, installation, and performance evaluation of permeable reactive barriers based on zero-valent iron.

    This book will be beneficial to engineers, scientists, and decision makers applying zero-valent iron for hazardous waste and inorganics removal.
