    This book provides a comprehensive and critical summary of clay mineral literature that relates to geology and geologic processes, making it useful both as a reference book for geologists and as a text for the specialist.The book encompasses the full scope of clay-shale geology. An introductory chapter provides basic background terminology and classification. This is followed by a relatively long chapter on the structure and composition of the various clay minerals. Chapter 3 provides an introduction to soil formation, chemical weathering, microbial alteration and the pedogenic formation of clay minerals. Chapters 4 and 5 cover the continental and marine transport, and deposition of clays. Both mechanisms and examples are presented, ranging from biodepositional to the nepheloid layer. Chapter 6 reviews data on the low to high temperature formation of clay minerals from marine volcanics, and the growth of authigenic clays in shallow marine, brackish, and evaporite environments. Chapter 7, Diagenesis Metamorphism, covers both burial diagenesis and the processes occurring during the conversion of shale to clay. Chapter 8 discusses the formation of authigenic-diageneti... formation of clays in sandstones. Chapter 9 describes the temperal distribution of clay minerals in North and South America, Europe, Africa and the Atlantic Ocean. The clay suites are related to factors such as continental drift, tectonics, climate and environment. The final brief chapter covers compaction, lithification and some general features of shales.The book is liberally sprinkled with x-ray patterns, chemical analyses, and SEM and TEM pictures, in addition to hundreds of examples.

  • Selective Sample Handling and Detection in High-Performance Liquid Chromatography

    • 1st Edition
    • Volume B
    • K. Zech + 1 more
    • English
    This is the second of a two-volume project which treats the handling, separation and detection of complex samples as an integrated, interconnected process. On the basis of this philosophy the editors have selected those contributions which demonstrate that optimal sample preparation leads to a simplification of detection or reduced demands on the separation process. Throughout the book emphasis is on chemical principles with minimum discussion of the equipment required - an approach which reflects the editors' view that the limiting factor in the analysis of complex samples is an incomplete knowledge of the underlying chemistry rather than the hardware available. This lack of knowledge becomes more evident as the demands for lower detection limits grow, as solving complex matrix problems requires a greater understanding of the chemical interaction between the substance to be analysed and the stationary phase. Thus, apart from one chapter dealing with chemically modified silicas, the main theme of the book is developed in three chapters on sample preparation and three on detection.The opening chapter outlines concentration and chromatography on chemically modified silicas with complexing properties, and gives examples of the use of these phases with organic and inorganic compounds. Chapter II, the first of the three contributions dealing with sample preparation, addresses such questions as whether the prepared sample is representative of the material to be analysed; how to avoid contamination; which separation procedure should be used to avoid tedious sample preparation. Chapter III describes the processing of whole blood for drug analysis. The determination of cyclosporine and its metabolites (an especially difficult case) demonstrates how comprehensive the optimisation of sample preparation must be to successfully perform the analysis. Several other examples are also given. Chapter IV deals with radio-column liquid chromatography and introduces the other theme of the book, i.e. selective detection methods. The widespread use of radioisotopes requires a high degree of purification during the manufacture of the compounds, as well as highly accurate detection methods in biological and biochemical studies.Chapter V continues the theme of selective detection with an overview of post-column reaction detection. The use of immobilised enzymes in post-column reactors or `pumpless' reactor systems for on-line reagent generation after the chromatographic separation step is discussed in detail. Various examples of the separation of biological compounds show how the production of electrochemical reagents and photochemical reaction detection have increased the selectivity of the detection, leading to more economical analytical systems. Selective detection employing luminescence detection techniques is outlined in Chapter VI. The use of immobilised fluorophores or the coupling to photochemical reactions leads to highly selective detection systems which can greatly simplify the sample handling. The final chapter reviews the use of continuous separation techniques in flow injection analysis thus revealing the need for a strong interdisciplinary dependence between sample handling and separation in this area.Written by experienced practitioners, this book will be extremely useful to investigators in many areas of application. Each chapter includes sufficient references to the literature to serve as a valuable starting point for more detailed investigation. The strong emphasis on sample handling makes the book unique in many ways and it will be welcomed by environmental scientists as well as those active in the clinical, pharmaceutical and bioanalytical fields.

    • English
    In Volume 30, an attempt is made to consider comprehensively both theoretical and experimental data that have been obtained to date on electron tunneling reactions involving chemical compounds of various classes, and to discuss the role played by these reactions in different areas of chemistry. The discussion of the above problem is preceded by a review of data on tunneling phenomena in nuclear physics, atomic physics, solid-state physics, as well as on the tunneling effects in chemistry that go beyond the framework of the main subject of this monograph. This review is included to acquaint the reader with the role of tunneling phenomena in physics and chemistry as a whole, to show how diversified the kingdom of tunneling phenomena is, and to see more distinctly the similarities and the differences between electron tunneling in chemical reactions and other tunnel phenomena.

  • Groundwater Resources Assessment

    • 1st Edition
    • Volume 38
    • J. Balek
    • English
    The development of environmentally sound groundwater resources has recently become a high priority throughout the world. Many countries are currently developing comprehensive regulations for the management of groundwater resources. Within this framework an assessment of renewable groundwater resources is one of the most important factors.This book is based on the author's many years of experience in the assessment of surface and subsurface water resources, field experiments and computer oriented work, in both developed and developing countries. An environmental approach is followed. Groundwater resources are seen as a part of the aquatic ecosystem in which not only geology but the whole lithosphere, vegetation, surface resources and atmosphere play an equally important role.Both simple and advanced models are presented, which can also be applied to complicated geological structures where standard groundwater models fail to operate. Conceptual and stochastic models are presented in a form which the reader can use as a guide for further model development - an approach much in demand in regions where many different features and a variety of data are available. Experimental work leading to the identification of groundwater resources is also broadly discussed.The book will prove valuable to students at university level, researchers, institutes, departments, and consultancies involved in water resources.

  • Interrelationships Between Microorganisms and Plants in Soil

    • 1st Edition
    • Volume 18
    • English
    These proceedings present the most up-to-date information on the interrelations between microorganisms and plants in the rhizosphere, and the possibility of utilizing these relationships to improve plant growth, health and yields. The application of some biological preparations may in the future partially replace the use of agrochemicals and thus contribute to environmental improvement and enhancement of the quality of soil, water and foodstuffs.The Symposium brought together specialists from fifteen countries to assess the advances in a field which has recently attracted considerable interest and is also important for society at large. The book contains over sixty contributions from rhizosphere microbiologists, focusing on the study of the function of microorganisms in the root system of crop plants and in its immediate vicinity, the effect of the plants themselves on this function, the interrelationships among different microorganisms in the rhizosphere and the elucidation of the mechanisms of microbial action in the agroecosystem. All these lines of research are intimately associated with the problems of soil fertility and crop yields, which in turn have a direct bearing on the nutrition of mankind and on environmental protection. The papers have been divided into four topics: symbiotic microorganisms in the root system; associative microorganisms in the root system; soil-borne phytopathogenic and phytotoxic microorganisms; and microbial preparations stimulating growth and improving the plant health. Each section starts with invited lectures from outstanding specialists. The work includes numerous tables, figures and references.The volume is primarily directed at soil microbiologists, plant pathologists and physiologists, ecologists as well as specialists in agronomy and environmental protection.
