‘Nanotechnology for Water Purification' is the newest addition to academic books in the area of nanotechnology. This book explores how different kind of nanomaterials and nanostructures can be used for water treatment. Each chapter carries in-depth research-based knowledge and review of state-of-art progress.
One of the most serious problems affecting humanity is the lack of water resources for human consumption. Worldwide 1.2 billion people do not have access to clean and safe drinking water and 2.4 billion people lack sanitation. Every year 5 million people die of waterborne diseases (World Health Organization, WHO). This situation is particularly dramatic in the least developed regions of Asia, Central and South America and Africa, where new water treatment processes are needed urgently. Problems with water are expected to grow worse in the coming decades, with water scarcity occurring globally, even in regions currently considered water-rich. Addressing these problems calls out for a tremendous amount of research to be conducted to identify new technologies for purifying water at lower cost and with less energy, while at the same time minimizing the use of chemicals and impact on the environment.
Nanotechnology has been identified as a technology that could play an important role in resolving many of the problems related to water purification and water quality. Nanomaterials and nanostructures have nano-scale dimensions in the range of 1 to 100 nm and often exhibit novel and significantly changed physical, chemical and biological properties. This is due to their structure, larger surface area per unit of volume and quantum effects that occur at the nano-scale.
Nanotechnology is a highly inter- and multi- disciplinary application oriented research area. Not only does it find its use in nanomedicine, solar cells, sensor development and so on, but can also be effectively utilized to prevent water pollution. Nanostructured materials such as magnetic nanoparticles, carbon nanotubes, silver-impregnated cyclodextrin nanocomposites, nanostructured iron-zeolites, carbo-iron nanomaterials, photocatalytic titania nanoparticles, nanofiltration membranes and functionalized silica nanoparticles can be employed in water treatment - to remove heavy metals, sediments, chemical effluents, charged particles, bacteria and other pathogens. This edited book comprises several review-style chapters written by world experts. The chapters are devoted to each of these nanotechnology based approaches: basic principles, practical applications, recent break-through and limitations associated with it. The last chapter covers the environmental risks of applying
engineered nanomaterials for water purification.
This book is available in paperback as well in e-book version through all major book sellers including publisher's website. Interested readers may wish to visit the web-page:
The wealth of information and insight offered in this book will be appealing to scientists and researchers over a wide range of disciplines.
