Nanomaterials have shown supreme potential in overcoming the major challenges posed by both the conventional as well as nanoenabled water purification systems. Remediation is the process of transforming the pollutants present in water from toxic to below the limits stipulated by national/international guidelines. Water remediation is the process of obtaining clean water from decontaminated water and is currently a huge challenge for the global scientific community. Volume 2 focuses on the use of inorganic oxides including metal and non-metal oxide materials for water remediation. This book also covers the broad discussion regarding various metal and non-metal oxides as well as nanoadsorbent metals, nanoparticles, cryogels and bentonites for the removal of the various organic and inorganic pollutants from wastewater. Water pollution is mainly caused by contaminants and can cause severe environmental and health issues. It is a well-established fact that nanomaterials have better adsorption capacity, selectivity and stability than nanoparticles. This book also covers the broad areas of nanotechnology, engineering, environmental science and water research, and will be of great benefit to researchers involved in these fields. The book provides a platform for all researchers as it covers considerable background from recent literature, including the abbreviations used. In addition, this book covers the broader research areas of chemistry, physics, materials science, composites, engineering and nanotechnology to present a multidisciplinary approach.
