Paper 4: Tests on mixtures of reference bentonite that had been equilibrated in vacuo four days with a 50 percent relative humidity gave quantitative relationships between weight loss and area under the differential thermal analysis (dta) low temperature endotherm, exchangeable calcium and first and second areas, under the dta low temperature endotherm, and exchangeable calcium and the x-ray d sub 001 spacing.
Download or read book Soil Chemistry and its Applications written by Malcolm Cresser and published by Cambridge University Press. This book was released on 1993-05-06 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: The central role of soil chemistry in the ecosystem and other disciplines is becoming increasingly important. For example the effects of the increased levels of atmospheric carbon dioxide, and accelerated use of pesticides, on soil fertility has been a focus of much high-level debate. This text begins by defining the relationship between soil chemistry and other fields such as plant science and pollution science. A detailed description of the components of soils follows, including inorganic, mineral and organic matter. The book addresses cogent issues such as soil fertility and soil pollution. In a concluding chapter, a review of future analytic advances in the study of soil chemistry is given, emphasising the importance of the soil chemist in equitable and sustainable land use and agricultural policy. The book is an ideal starting point for the student undertaking undergraduate study in the environmental and soil sciences.

Download or read book Physicochemical Theory of Effective Stress in Soils written by V.I. Osipov and published by Springer. This book was released on 2015-09-16 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a new theory of effective stresses in soils, which takes into account the internal stresses caused by the molecular, electrostatic, and structural mechanical forces. These forces exist in thin hydrate films of adsorbed water molecules at the contacts of structural elements, producing the so-called disjoining effect. They can be evaluated by incorporating theoretical achievements of molecular physics and colloidal chemistry. The novel theory described in this book considers not only external but also internal stresses and gives different results for effective forces compared with the Terzaghi theory widely applied in soil mechanics. The book provides equations for the actual effective stresses at the contacts of particles, thus improving the Terzaghi theory in physicochemical context.

Download or read book Physicochemical Hydrodynamics written by Ronald F. Probstein and published by Butterworth-Heinemann. This book was released on 2013-10-22 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physicochemical Hydrodynamics: An Introduction aims to provide an introduction to physicochemical hydrodynamics (PCH), which deals with the interaction between fluid flow and physical, chemical, and biochemical processes. PCH has applications in many areas of science and technology and is a rapidly expanding field. Emphasis of this book is on rational theory and its consequences, with the purpose of showing the underlying unity of PCH, in which diverse phenomena can be described in physically and mathematically similar ways. The magic of this unity is shown in the similar manner in which solutes concentrate in a flow containing chemically reacting surfaces, reverse osmosis membranes, and electrodialysis membranes or the similarity of particle motions in sedimentation, centrifugation, ultrafiltration, and electrophoresis. Problems are included at the end of each chapter and are ordered following the sequence in which the material is set out. The questions range in difficulty, with most requiring an analytic development, but with some asking only for a descriptive answer. All problems are intended to illustrate the ideas presented, though often the solution goes beyond the explicit discussion in the book, with the answer constituting a generalization or extension of the text material. This book is an essential source of information for students majoring in the field of PCH.

Download or read book Bioavailability of Contaminants in Soils and Sediments written by National Research Council and published by National Academies Press. This book was released on 2003-05-03 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bioavailability refers to the extent to which humans and ecological receptors are exposed to contaminants in soil or sediment. The concept of bioavailability has recently piqued the interest of the hazardous waste industry as an important consideration in deciding how much waste to clean up. The rationale is that if contaminants in soil and sediment are not bioavailable, then more contaminant mass can be left in place without creating additional risk. A new NRC report notes that the potential for the consideration of bioavailability to influence decision-making is greatest where certain chemical, environmental, and regulatory factors align. The current use of bioavailability in risk assessment and hazardous waste cleanup regulations is demystified, and acceptable tools and models for bioavailability assessment are discussed and ranked according to seven criteria. Finally, the intimate link between bioavailability and bioremediation is explored. The report concludes with suggestions for moving bioavailability forward in the regulatory arena for both soil and sediment cleanup.

Available in PDF, EPUB and Kindle. Book excerpt: This Encyclopedia of Agrophysics will provide up-to-date information on the physical properties and processes affecting the quality of the environment and plant production. It will be a "first-up" volume which will nicely complement the recently published Encyclopedia of Soil Science, (November 2007) which was published in the same series. In a single authoritative volume a collection of about 250 informative articles and ca 400 glossary terms covering all aspects of agrophysics will be presented. The authors will be renowned specialists in various aspects in agrophysics from a wide variety of countries. Agrophysics is important both for research and practical use not only in agriculture, but also in areas like environmental science, land reclamation, food processing etc. Agrophysics is a relatively new interdisciplinary field closely related to Agrochemistry, Agrobiology, Agroclimatology and Agroecology. Nowadays it has been fully accepted as an agricultural and environmental discipline. As such this Encyclopedia volume will be an indispensable working tool for scientists and practitioners from different disciplines, like agriculture, soil science, geosciences, environmental science, geography, and engineering.
