Description

Biochar Application in Soil to Immobilize Heavy Metals: Fundamentals and Case Studies covers biochar’s application to soil heavy metal immobilization. The book covers biochar’s effect on soil micro-and macro-properties, assessment of heavy metal stability in biochar-treated soil, and long-term stability of heavy metals in biochar-treated soil. A notable feature of this book includes its extensive use of case studies. Chapters focus on small-scale field trials and medium to large-scale industrial applications of biochar to immobilize soil heavy metals. In addition, the flow of the whole book follows “mechanisms-to-applications-to-case studies,” allowing readers to translate the fundamentals to practical applications.This book provides soil and environmental scientists with the tools they need to build the links between micro-level surface chemistry and macro-level engineering performance.

Key Features

  • Covers the fundamentals and influence of pyrolysis temperature and feedstock on the fundamentals, which is very important for applications
  • Includes sections that discuss the molecular interaction between biochar and heavy metals in soil
  • Contains chapters with subsections that cover mechanisms, applications and case studies, thus allowing readers to quickly grasp content

Readership

Students, Professors, Researchers, and other professionals and stakeholders working in Soil Science and Environmental Science. Environmental Engineers, Agricultural Engineers, Geo-engineers
