Studies the Environmental, Cosmetic, and Pharmaceutical Applications of Bentonite Clay Bentonite clay, of which members of the smectite family of clay minerals are particularly important, has proven to be effective in sealing off wastes from groundwater. Bentonite Clay: Environmental Properties and Applications explores the mineralogy of clays in general and of smectites in particular that represent challenging conditions for geotechnical professionals responsible for earth dam construction, the foundations of roads and buildings, and the long-term isolation of chemical and radioactive wastes. The author, a world-renowned expert on the subject, places special emphasis on the environmental behavior of bentonite clay when focused on the isolation of hazardous wastes and also considers its use in cosmetics and pharmaceuticals. Based on classical literature and current research and development, this text provides an in-depth introduction to bentonite soil, explains the origin of smectite-rich clays, and pinpoints where they can be found. The book describes the interaction of expandable clay minerals, gas, and fluids, followed by a description of the physical and chemical properties of smectite clay saturated with water or chemical solutions. It also provides relevant findings and conclusions concerning the function of bentonite-based sealing repositories for dangerous waste. This text: Describes the constitution of smectite minerals as a basis for understanding the behavior of smectite clays and their performance in the isolation of hazardous waste Factors in the longevity of smectite clays in bentonite beds and in the form of canister-embedding buffers in repositories for deep geological disposal of highly radioactive waste (HLW) Covers the design principles for clay seals and considers their function in the isolation of waste and redirecting groundwater flow Bentonite Clay: Environmental Properties and Applications documents the origin, properties, and characteristics of bentonite and its uses.

The first general texts on clay mineralogy and the practical applications of clay, written by R.E. Grim, were published some 40-50 years ago. Since then, a vast literature has accumulated but this information is scattered and not always accessible. The Handbook of Clay Science aims at assembling the scattered literature on the varied and diverse aspects that make up the discipline of clay science. The topics covered range from the fundamental structures (including textures) and properties of clays and clay minerals, through their environmental, health and industrial applications, to their analysis and characterization by modern instrumental techniques. Also included are the clay-microbe interaction, layered double hydroxides, zeolites, cement hydrates, genesis of clay minerals as well as the history and teaching of clay science. No modern book in the English language is available that is as comprehensive and wide-ranging in coverage as the Handbook of Clay Science. In providing a critical and up-to-date assessment of the accumulated information, this will serve as the first point of entry into the literature for both newcomers and graduate students, while for research scientists, university teachers, industrial chemists, and environmental engineers the book will become a standard reference text. * Presents contributions from 66 authors from 18 different countries who have come together to produce the most comprehensive modern handbook on clay science * Provides up-to-date concepts, properties, and reactivity of clays and clay minerals in a one-stop source of information * Covers classical and new environmental, industrial, and health applications of clays, as well as the instrumental techniques for clay mineral analysis * Combines geology, mineralogy, crystallography with physics, geotechnology, and soil mechanics together with inorganic, organic, physical, and colloid chemistry for a truly multidisciplinary approach

This book is an attempt to provide a comprehensive and coherent description of three widely separated aspects of clays: the science of clays; the industrial uses of clays; and the role of clays in the environment. Most of the existing literature lacks such an integrated study and this work endeavours to fill that gap. An exhaustive account of the science of clays is presented in Part I of the book, which includes the classification, origin and evolution, composition and internal structure, chemical and physical properties of clays; soil mechanics; and analytical techniques for determining clay constituents. Part II provides a comprehensive description of the applications of clays and their derivatives in various industries, while Part III describes the role of clays in the environment; the pollution caused by clay minerals; and the application of clays in order to prevent environmental hazards. A principal feature of the book is its explanation of how the structure and composition of particular clay types facilitate their specific industrial or environmental applications, thus describing the interrelationship between three widely varying aspects of clay. A number of thought-provoking questions are raised at the end of the work in order to leave readers with a better insight in this regard.
