This second volume of Metal-Organic Framework Composites focusses on water pollution as a major concern and endangerment to human health and the application of MOFs for remediation. Metal-organic frameworks (MOFs) are advanced porous materials and are promising adsorbents with facile modifications, high specific surface area, controllable porosity, and tailored surface properties. The authors systematically cover the synthesis of ZIF-8 base composites and discuss the role of ZIF-8 composites in water decontamination as an adsorbent and photocatalyst.

The book offers a comprehensive overview of the latest improvements and concerns with respect to membrane fouling remediation techniques, issues of bioincompatibility for biomedical applications, and various subareas of membrane separation processes, which will be an efficient resource for engineers.

Water is the most vital substance in every aspect of life, and its contamination because of the activity of mankind poses a big global challenge. Addressing this issue for drinking purposes and environmental protection is the current big issue. Many research groups worldwide have been working on effective treatment technologies based on nanomaterials during the last two decades. Water and wastewater treatment by nanomaterial-based technologies has become an aid in finding possible solutions for contaminated wastewater released from various water sources. Nanoscale materials can be seen to take on unique and unpredictable properties that make them more robust, flexible, lighter, and faster, and the particular material used for the development of devices and systems. Features: • This book presents the use of different advanced nanomaterials to treat water and wastewater. • The uses of carbon-based nanomaterials, metal-organic frameworks (MOFs), and biopolymer-supported nanomaterials for water treatment are explored, focusing on new- generation materials. • Water purification methods such as the disinfection of water using green synthesized nanomaterials, adsorption through nanomaterial-based adsorbents, and nanofiltration techniques are discussed. We emphasize efficient water treatment methods and the use of new emerging nanomaterials in the toxicological study of nanomaterials. Nanomaterials provide high-performance and cost-effective treatment for water treatment. Various nanomaterials and electrochemical methods are used to stop, remove, or neutralize water harmful organic and inorganic contaminants in water through adsorption, filtration, and disinfection.

This book aims at illustrating several examples of different membrane compositions ranging from inorganic, polymeric, metallic, metal organic framework, and composite which have been successfully deployed to separate industrially relevant gas mixtures including hydrogen, nitrogen, methane, carbon dioxide, olefins/parafins among others. Each book chapter highlights some of the current and key fundamental and technological challenges for these membranes that must be overcome in order to envision its application at industrial level.

The growth of interest in newly developed porous materials has prompted the writing of this book for those who have the need to make meaningful measurements without the benefit of years of experience. One might consider this new book as the 4th edition of "Powder Surface Area and Porosity" (Lowell & Shields), but for this new edition we set out to incorporate recent developments in the understanding of fluids in many types of porous materials, not just powders. Based on this, we felt that it would be prudent to change the title to "Characterization of Porous Solids and Powders: Surface Area, Porosity and Density". This book gives a unique overview of principles associated with the characterization of solids with regard to their surface area, pore size, pore volume and density. It covers methods based on gas adsorption (both physi and chemisorption), mercury porosimetry and pycnometry. Not only are the theoretical and experimental basics of these techniques presented in detail but also, in light of the tremendous progress made in recent years in materials science and nanotechnology, the most recent developments are described. In particular, the application of classical theories and methods for pore size analysis are contrasted with the most advanced microscopic theories based on statistical mechanics (e.g. Density Functional Theory and Molecular Simulation). The characterization of heterogeneous catalysts is more prominent than in earlier editions; the sections on mercury porosimetry and particularly chemisorption have been updated and greatly expanded.

Rapid population growth, urbanisation and industrialisation have caused serious problems in terms of water pollution and the supply of safe water. Solutions for monitoring pollutants in water and for removing them are urgently needed and they must be both efficient and sustainable. Recent advances in emerging environmental nanotechnologies provide promising solutions for these issues. The physical and chemical properties of nanomaterials can be tailored by controlling attributes such as their size, shape, composition, and surface, so that they can be both highly specific and highly efficient. This makes them perfect platforms for a variety of environmental applications including sensing, treatment and remediation. Providing an array of cutting-edge nanotechnology research in water applications, including sensing, treatment, and remediation, as well as a discussion of progress in the rational design and engineering of nanomaterials for environmental applications, this book is a valuable reference for researchers working in applications for nanotechnology, environmental chemistry and environmental engineering as well as those working in the water treatment industry.
