Download and read online ebook Metal Speciation and Contamination of Soil write by Herbert E. Allen. This book was released on 1994-11-29. Metal Speciation and Contamination of Soil available in PDF, EPUB and Kindle. Metal Speciation and Contamination of Soil provides a thorough overview of the biogeochemical processes governing the behavior, transport, and bioavailability of heavy metals in contaminated soils and suggests alternative approaches for effective remediation. This important new book contains contributions from experts in various disciplines who explore the issues from theoretical, experimental, and pragmatic perspectives. Topics include redox chemistry, kinetics of metal reactions, spectroscopic characterization of metal ion reactions at surface, modeling hydrologic transport phenomena and colloid-associated transport of metals through the soil profile to ground water, and remediation alternatives.

The elevated heavy metal contamination in soils has given rise to the accurate assessment of the availability and mobility of heavy metals and the development of remediation strategies. In this study, soi! column-Donnan membrane technique (SC-DMT) and diffusive gradients in thin¬films gels (DGT) were used to measure the concentration and speciation of Cd, Cu, Ni, Pb, and Zn in eighteen soil solutions, covering a wide range of metal sources (natural and anthropogenic) and concentrations. The availability of Cd, Cu, Pb, and Zn in nine contaminated soils was evaluated by combining chemical extractions with multi-elementary stable isotopic dilution (ID) method. The isotopically exchangeable pool and the operationally defined pool determined by chemical extractions were then compared to probe the relationships between metal availabilities and their bearing phases. The mufti-surface model was used to assess the rote of the major soil components (organic matter, clay, iron hydroxides, and manganese hydroxides) in controlling metal availability. The combination of analytical approaches and speciation modeling can provide mutual validation and a more comprehensive picture of the availability of metals. In our work, model calculation generally provided an adequate prediction of metal speciation in soi! solution and solid phase, and it can be a promising tool to decipher the underlying mechanisms of the differences in metal availabilities in soils.

Download and read online ebook Heavy Metals Release in Soils write by H. Magdi Selim. This book was released on 2001-06-15. Heavy Metals Release in Soils available in PDF, EPUB and Kindle. Understanding the mechanisms associated with metal complexes and the sequestering metal contaminants in the environment is essential for effective remediation. Heavy Metal Release in Soils describes and quantifies desorption/release kinetics and dissolution reactions in the release of heavy metals from soil. The book focuses on: New techniques - microscopic surface techniques, NMR and electrophoresis, XAFS, SFM, and time-resolved ATR-FTIR Theoretical analysis and kinetic approaches - adsorption/desorption hysteresis, competitive sorption and transport, multi-component models, speciation kinetics, isotherms and soil and metal parameters, and the role of soil properties on transport Applications - arsenic speciation and mobility in contaminated soils, modeling activity of CD, Zn, and Cu in contaminated soils, and in situ chemical immobilization A timely addition to the literature, this book highlights the desorption/release mechanisms for the purpose of resolving remediation dilemmas in contaminated environments. It gives you the added advantage of case studies at both the microscopic and macroscopic scales, and provides both experimental and numerical investigations. With contributions from an international panel of authors, Heavy Metals Release in Soils fills a gap in the current literature concerned with subsurface contaminant fate and transport processes.
