DOWNLOAD EBOOKClay and clay minerals have always been used since the ancient times for making ceramic materials and also as a building material. Over the past decades, there has been a growing trend in their applicability in different areas such as industries, environmental remediation and water treatment sectors. The growing trend is mainly associated with the fact that they are chemically and mechanically stable, have higher specific surface area and cation exchange capacity. Furthermore, clays can be modified to improve their functionalities in different sectors. In this chapter, we present a review of the structural, mineralogical and chemical properties of clay and the effect of surface modification in their structures. We further looked at their applicability in arsenic and fluoride removal in their raw and also in their modified form. Although the literature showed that modified clay minerals yields higher adsorption capacity as compared to raw clays little nothing has been reported yet in relation to the cost of modifying clays with chemical species. As such new studies should also elaborate on the cost effectiveness of modifying clay minerals with chemical species.

DOWNLOAD EBOOKThis book on Applied Clay Mineralogy is comprehensive. It covers the structure, composition, and physical and chemical properties of kaolinite, halloysite, ball clays; bentonites including sodium montmorillonite, calcium montmorillonite, and hectorite; and palygorskite and sepiolite. There is also a short chapter on common clays which are used for making structural clay products and lightweight aggregate. The location and geology of the major clay deposits that are marketed worldwide and regionally include kaolins from the United States, Southwest England, Brazil, and the Czech Republic along with halloysite from New Zealand and ball clays from the US, England, Germany, and Ukraine. Bentonites from the U.S. and Europe are included along with palygorskite and sepiolite from the U.S., China, Senegal, and Spain. The mining and processing of the various clays are described. Extensive discussions of the many applications of the clays are included. The appendices cover the important laboratory tests that are used to identify and evaluate the various types of clay. Many figures are included covering electron micrographs, processing flow sheets, stratigraphy, and location maps. * Provides the structure and composition of clay minerals, as well as their phyisical and chemical properties * Discusses pplications for Kaolin, Bentonite, Palygorskite and Sepiolite * Contains appendixes of laboratory tests and procedures, as well as a test for common clays

DOWNLOAD EBOOKOf huge relevance in a number of fields, this is a survey of the different processes of soil clay mineral formation and the consequences of these processes concerning the soil ecosystem, especially plant and mineral. Two independent systems form soil materials. The first is the interaction of rocks and water, unstable minerals adjusting to surface conditions. The second is the interaction of the biosphere with clays in the upper parts of alteration profiles.

DOWNLOAD EBOOKA comprehensive review of environmental remediation is presented with an emphasis on the role of clay minerals in water purification. In the first chapter, important aspects of environmental problems and possible solutions are discussed. In the second chapter, the application of natural clay minerals as environmental cleaning agents are explained. The discussion is focused on the role of different types of clay materials in hazardous substance removal from air, aqueous solutions, wastewater, aquaculture, ground water, etc. In the next chapter, the modification of clay materials is explored including the preparation of clay composite materials for environmental remediation. Various aspects of clay material modifications and the effects of clay surface chemistry on the removal of hazardous material is also discussed. Next, the equilibrium and kinetics of hazardous substance adsorption is presented. This chapter summarizes recent studies on the removal of hazardous substances from aqueous solutions and the environment using various types of clay minerals. The brief also includes various models used in adsorption studies and touches on the characterization of clay minerals.

DOWNLOAD EBOOKThis volume provides a comprehensive academic review of both positive and negative effects of minerals on human health and quality of life. The book adopts the concept of mineral latu sensu (mineral l.s.), which encompasses a broad spectrum of natural, inorganic, solid, and crystalline, of natural and inorganic chemical elements (metals and metalloids), of modified natural minerals, of biominerals, and of syntetic minerals, all products that branch across the disciplines of earth, soil, environmental, materials, nutrition, and health sciences. Using this broad framework, the authors are able to provide a multidisciplinary assessment on many types of minerals which can be essential, beneficial and hazardous to human health, covering applications in medical geology, medical hydrology or balneotherapy, pharmacology, chemistry, nutrition, and biophysics. The book performs historical analyses of the uses of minerals for therapeutic and cosmetic purposes to better understand current trends and developments in mineral research and human health. The book will be of interest to students, public health officials, environmental agencies and researchers from various disciplines, as well as scientific societies and organizations focusing on medical geology, health resort medicine (crenotherapy, hydrotherapy and climatotherapy), and on pharmaceutical, cosmetic and biomedical applications.

DOWNLOAD EBOOKClay is an abundant raw material which has a variety of uses and properties depending on their structure and composition. Clay minerals are inexpensive and environmentally friendly naturally occurring nanomaterials, thanks to their 1 nm thick silicate layers, in all types of sediments and sedimentary rocks. The book chapters have been classified according to their characteristics in topics and applications. Therefore, in the first section five chapters is dedicated to the characterization and utilization of clay minerals in deposits. The second section includes four chapters about the significance of clay minerals in soils. Third section is devoted to different aspects of clay minerals research, especially to the characterization of structure and modifications for their application.
