Book Description
This book introduces the use of bio-waste as a raw material for the preparation of activated carbon (AC) for dyes removal. Activated carbon was derived from assorted materials that have potential to function as a good adsorbent, especially for dyes removal in wastewater treatment. This book was written as a case study to help readers understand the function of AC in each system and approach. This book includes applications of AC derived from corncob; palm tree empty fruit bunch; seashell; eggshell; spent coffee ground; rubber wood saw dust; kenaf fiber and coconut frond in dyes removal and wastewater treatment. The efficiency of activated carbon prepared from various bio-wastes is evaluated by calculating the removal rate of dyes in wastewater. This unique book features eight chapters pertinent to the current situation, as loads of dye effluent are being discharged into the environment. The characterization of the produced AC is analysed using various instrumentations such as scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIRS) and X-ray diffraction (XRD). The book will attract Eastern and Western researchers and scholars at all levels of degree qualification, industrial practitioners and entrepreneurs in the field of bio-waste.

Book Description
Pollution due to various anthropogenic activities continues to increase. In terms of water pollutants, organic and inorganic pollutants are the most problematic. Although several measures have been proposed and implemented to prevent or reduce contamination, their increased concentration in water bodies has created serious concerns. Over the years, the problem has been aggravated by industrialization, urbanization and the exploitation of natural resources. The direct discharge of wastewater contaminants and their geographical mobilization have caused an increase in concentration in ground, surface, fluvial and residual waters. Extensive information about detection and disposal methods is needed in order to develop technological solutions for a variety of environments, both urban and rural. This book provides up-to-date information on wastewater contaminants, aimed at researchers, engineers and technologists working in this field. Conventional physicochemical techniques used to remove contaminants from wastewater include ion exchange, precipitation, degradation, coagulation, coating, membrane processes and adsorption. However, these applications have technological and economic limitations, and involve the release of large amounts of chemical reagents and by-products that are themselves difficult to remove. Biosorption - the use of organically generated material as an adsorbent – is attracting new research and scholarship. Thermally-treated calcined biomaterials may be treated to remove heavy metals from wastewater. To ensure the elimination of these contaminants, existing solutions must be integrated with intelligent biosorption functions. Biosorption for Wastewater Contaminants will find an appreciative audience among academics and postgraduates working in the fields of environmental biotechnology, environmental engineering, wastewater treatment technology and environmental chemistry.

Book Description
Biochar is a carbon-rich material produced from the pyrolysis of organic materials from agricultural and forestry biomass at a relatively low temperature in the absence of oxygen. As such, it has potential for solving many agricultural and environmental problems.This book is divided into five sections: “Introduction,” “Production and Legislation of Biochar,” “Applications of Biochar for Soil Fertility Improvement,” “Role of Biochar for Soil Remediation and Ameliorating Salinity Effects” and “Applications of Biochar for Water Treatment.” Chapters address topics such as the pros and cons of biochar, its production, and its role in remediating and treating contaminated soils and water.

Book Description
Metals can be dispersed, both naturally and by man's activities, into any of the Earth's elements - soil, water or air. Biological techniques for removing metal pollutants from soil, air or water are now attracting great interest, both because they are seen as more environmentally friendly than chemical treatments, and because, in some cases at lea

Book Description
This book presents natural minerals used as inorganic materials, and inorganic materials exchanging cations or anions in natural minerals for other ions not found in nature. In addition, composites such as natural mineral materials that interact with organic molecules or polymers are introduced according to how they are used. Readers can refer to this volume as a guidebook to search for specific inorganic materials, and, if they wish, can consult any part of it at random. The book will be especially helpful and of interest to both scientists and engineers.

Book Description
Metal Oxides in Supercapacitors addresses the fundamentals of metal oxide-based supercapacitors and provides an overview of recent advancements in this area. Metal oxides attract most of the materials scientists use due to their excellent physico-chemical properties and stability in electrochemical systems. This justification for the usage of metal oxides as electrode materials in supercapacitors is their potential to attain high capacitance at low cost. After providing the principles, the heart of the book discusses recent advances, including: binary metal oxides-based supercapacitors, nanotechnology, ternary metal oxides, polyoxometalates and hybrids. Moreover, the factors affecting the charge storage mechanism of metal oxides are explored in detail. The electrolytes, which are the soul of supercapacitors and a mostly ignored character of investigations, are also exposed in depth, as is the fabrication and design of supercapacitors and their merits and demerits. Lastly, the market status of supercapacitors and a discussion pointing out the future scope and directions of next generation metal oxides based supercapacitors is explored, making this a comprehensive book on the latest, cutting-edge research in the field. - Explores the most recent advances made in metal oxides in supercapacitors - Discusses cutting-edge nanotechnology for supercapacitors - Includes fundamental properties of metal oxides in supercapacitors that can be used to guide and promote technology development - Contains contributions from leading international scientists active in supercapacitor research and manufacturing
