Serious challenges instigated by pollution are driving research seeking feasible strategies for social, economic, and environmental sustainability. The fascinating science of selective adsorbents of heavy- or precious-metal pollutants such as lead, mercury, gold, and silver ions has attracted investigation by many capable materials scientists, chemists, and environmental engineers, resulting in rapidly increasing progress with time. This book reveals theoretical and practical information that will assist in the study, research, and innovations of effective adsorbents towards toxic and noble metal ions. It allows the reader to pursue an answer to this mystery through interdisciplinary scientific knowledge of material design, synthesis, and environmental purification of strong adsorbents, as has never been presented systematically before, demonstrating the nature of the unique molecular and morphological structures of the adsorbent and how to design and optimize molecular and material structures.

When applying human ingenuity and experience to natural resources and processes, scientists and researchers can maximize the potential of nature for human benefit. In that vein, this book explores the latest breakthroughs in natural biopolymers, green composites, and green nanocomposites, a field that is rapidly expanding. The volume looks at bio-based polymers and composites for environmental sustainability, such as in bioremediation and for wastewater treatment. It discusses natural polymers from waste products and considers the use of bio-based polymers and composites in fertilization in horticulture as well as in industry and construction, such as for recycling of concrete, for gas sensing applications for safety, for fiber-reinforced epoxy composites, etc.

b”Application of Nanotechnology in Mining ProcessesNanotechnology has revolutionized processes in many industries but its application in the mining industry has not been widely discussed. This unique book provides an overview of the successful implementation of nanotechnology in some of the key environmental and beneficiation mining processes. This book explores extensively the potential of nanotechnology to revolutionize the mining industry which has been relying for a very long on processes with limited efficiencies. The nine specialized chapters focus on applying nanoflotation to improve mineral processing, effective extraction of metals from leachates or pregnant solutions using nanoscale supramolecular hosts, and development of nano-adsorbents or nano-based strategies for the remediation or valorization of AMD. The application of nanotechnology in mining has so far received little attention from the industry and researchers and this groundbreaking book features critical issues so far under-reported in the literature: Application of nanotechnology in mineral processing for the enhancement of froth flotation Development of smart nanomaterials and application for the treatment of acid mine drainage Recovery of values from pregnant solutions using nanoadsorbents Valorization of AMD through formation of multipurpose nanoproducts. Audience Industrial interest will be from mining plant operators, environmental managers, water treatment plants managers, and operators. Researchers in nanotechnology, environmental science, mining, and metallurgy engineering will find the book valuable, as will government entities such as regulatory bodies officers and environmentalists.

Illustrating developments in electrochemical nanotechnology, heterogeneous catalysis, surface science and theoretical modelling, this reference describes the manipulation, characterization, control, and application of nanoparticles for enhanced catalytic activity and selectivity. It also offers experimental and synthetic strategies in nanoscale surface science. This standard-setting work clariefies several practical methods used to control the size, shape, crystal structure, and composition of nanoparticles; simulate metal-support interactions; predict nanoparticle behavior; enhance catalytic rates in gas phases; and examine catalytic functions on wet and dry surfaces.

Porosity in carbons often means different things to different people depending largely on the different applications of the various carbon materials. On the one hand, users involved in gas purification or respiratory protection are concerned primarily with microporosity, and at the other extreme, the user of carbon in the form of metallurgical coke is concerned with macroporosity because of its influence on the mechanical properties of the coke. Between these extremes there is a range of applications which rely on different aspects of the nature of the porous structure and the characterization required reflects the particular application in mind. This characterization of a wide diversity of porous structures presents some problems. However recent developments have produced some solutions, for example computerized image analysis has facilitated the measurement of pore shape and size. The eleven chapters in this book present an analysis of the current methods of characterization and the role of various aspects of carbon porosity in some representative and diverse applications.

This practical book combines recent progress with a discussion of the general aspects of catalyst preparation. The first part deals with the basic principles of solid catalyst preparation, explaining the main aspects of sol-gel chemistry and interfacial chemistry, followed by such techniques as co-precipitation and immobilization. New tools for catalyst preparation research, including microspectroscopy and high-throughput experimentation, are also taken into account. The second part heightens the practical relevance by providing six case studies on such topics as the preparation of zeolites, hydrotreating catalysts, methanol catalysts and gold catalysts
