Aquatic Surface Chemistry by Werner Stumm Pdf

This comprehensive contributed volume presents an account of current research and applications of chemical processes occurring at the interfaces of water with naturally occuring solids. Interactions of solutes with the solid surfaces are looked at from a mechanistic and dynamic point of view rather than a descriptive one. Processes discussed and concepts presented are applicable to all natural waters (oceans and fresh waters as well as soil and sediment water systems) and to the surfaces of natural solids such as minerals, soils, sediments, biota, and humus. Chapters progress from theoretical models and laboratory studies to applications in natural water, soil, and geochemical systems, emphasizing those processes that regulate the distribution and concentration of elements and compounds. Topics covered include adsorption mechanisms in aquatic surface chemistry, the electric double layer at the solid-solution interface, aspects of molecular structure in surface complexes: spectroscopic investigations, interpretation of metal complexation by heterogeneous complexants, the role of colloids in the partitioning of solutes in natural waters, and 'from molecules to planetary environments': understanding global change.

Natural and Engineered Clay Barriers by Anonim Pdf

Clays are used as barriers for the isolation of landfills and contaminated sites. They are envisioned as long-term storage media for hazardous materials and radioactive wastes, and as seals in the case of geological CO2 sequestration or energy storage. Clay properties greatly influence the integrity, efficiency, and safety of these applications. Natural and Engineered Clay Barriers provides a clear view of the fundamental properties of clay materials and how these properties affect their engineering applications. This volume focuses on how the mass transfer properties (hydraulic permeability, gas fluxes, molecular diffusion, semi-permeable membrane properties), geochemical reactivity (adsorption, dissolution) and mechanical properties of clay barriers at the macroscale are influenced by phenomena that occur at clay mineral - water interfaces. Examines clay properties from the molecular to the macroscopic scale Addresses experimental and modeling issues Authored by experts in the properties of clay barriers

Particle Deposition and Aggregation by M. Elimelech,Xiadong Jia,John Gregory,Richard Williams Pdf

Deposition and aggregation of small solid particles are encountered in many natural and industrial environments. Whether it be deposition of particles onto a surface immersed in a liquid suspension or aggregateion of individual particles, these processes are of enotmous significance. They are vital to the manufacture of magnetic tape, purification of water using packed bed filters, selective capture of solids, cells and macromolecular species, and many other applications. This book presents a unified approach to the measurement, modelling and simulation of these processes, bringing together the disciplines of colliod and surface chemistry, hydrodynamics, and experimental and computational methods. It will be required reading for graduates working in process and environmental engineering, postgraduates involved in industrial R & D and for all scientists wishing to gain a more detailed and realistic understanding of process conditions in these areas.

The Chemistry of Soils by Garrison Sposito Pdf

There have been many advances in soil chemistry since Oxford published the first edition of The Chemistry of Soils in 1989. The physical-chemistry approach to soil chemistry taken in the book, groundbreaking for its time, has been adopted by nearly every soil chemistry book published since. This book offers a thorough update of all topics covered in the previous edition. In the last 16 years, soil chemistry as a discipline has assumed major significance in connection with global climate change. The 2nd edition addresses the emergent issue of global climate change by exploring the interaction between organic carbon and soil. The largest repository of organic carbon on earth is still soil, and the process by which organic carbon is sequestered by soil, thus preventing the release of carbon dioxide into the atmosphere, is one of the proper concerns of soil chemistry. Thus, the revision provides a rigorous discussion of soil chemistry in its broader environmental and biogeochemical contexts.
